Callback in chrome.tab.create to open proprietary schema URL is not invoked

What do you want to do

After creating a tab by passing the URL of its own protocol to the WebExtensions chrome.tab.create, the OS launches an app that supports its own protocol.

Then I want to remove unnecessary tabs.

Problems

The callback method passed to the second argument of chrome.tab.create is not invoked.

Sample Code

/**background.js**/

functionOpenNiconicoProtocol(niocnicoUrl="niconico://sm9")
{
    chrome.tabs.create({url:niocicoUrl, active:false}, OnTabCreated);
}

function OnTabCreated(tabInfo)
{
    console.log("tabid" + tabInfo.id);
    chrome.tabs.remove(tabInfo.id,()=> 
    {
        if(chrome.runtime.lastError){
            console.log("failed:"+chrome.runtime.lastError);
        } else{
            console.log("removed tab");
        }
    });

}

Can't I get a callback for tabs.create with my own protocol URL?

Self-resolved.

For custom URI schemas, callbacks passed to the second argument of chrome.tabs.create are not invoked (we could not determine if this was a bug or specification).

Obtain tabs created with custom URI schemas in chrome.tabs.query and close them manually.

One caveat is that if the custom URI schema does not contain the host element, the urlPattern in chrome.tabs.query({url:urlPattern}) may determine the invalid pattern.

 function OpenNiconicoProtocol (niocnicoUrl)
    {
        chrome.tabs.query({currentWindow:true, active:true}, function(maybeCurrentTab){
            varcurrentTab=maybeCurrentTab[0];

            // open as a new tab
            chrome.tabs.create({url:niocicoUrl, active:false});

            // Custom Scheme URL Does Not Call Back Tabs.create
            // close unnecessary tabs in a little while
            setTimeout(function(){
                // The url you give to query is a custom scheme and
                // For URL patterns without host parts
                // Invalid pattern and unsupported
                // Obtain all tabs and avoid unnecessary tabs sequentially 
                chrome.tabs.query({},(tabs)=> 
                {
                        if (tabs&tabs.length)
                        {
                            for (vartabIndex intabs)
                            {
                                vartab=tabs [tabIndex];
                                varisRemoveTarget=false;
                                if(tab.url&isNiconicoSchemeUrl(tab.url))
                                {
                                    isRemoveTarget=true;
                                }
                                else if (currentTab.index<tabIndex)
                                {
                                    // Pages that are not rendered as http are:
                                    // Tab.url seems to remain about:blank (check Firefox)
                                    // Target blank page tabs that appear to be newer than the current tab
                                    if(tab.url&tab.url=="about:blank")
                                    {
                                        isRemoveTarget=true;
                                    }
                                }
                                
                                if(isRemoveTarget)
                                {
                                    chrome.tabs.remove(tab.id,()=> 
                                    {
                                        if(chrome.runtime.lastError){
                                            console.log("failed:"+chrome.runtime.lastError);
                                        } else{
                                            console.log("removed tab");
                                        }
                                    });
                                }                               
                            }
                        }
                });
            }, 1000);
