Steps to reproduce the problem:
An extension cannot open a custom URI link without opening a blank tab.

I have created below an example that will create an extension that adds a context menu item to "launch the link with the custom URI" for all links on a page. 

On firefox, this works. It opens the custom action URI, then it prompts "Do you want to launch this in your CustomAppNameHere?" meanwhile the script closes the empty tab. But when it closes the empty tab the prompt stays.

In chrome/chromium, when the tab is closed, so is the dialog to launch the page in the custom app.

see comments on this question https://stackoverflow.com/questions/52639875/how-to-launch-a-custom-uri-from-an-extension-without-leaving-an-empty-tab-open?noredirect=1#comment92213224_52639875 for some other things we tried. 

function handleClick(info, tab) {
  chrome.tabs.create({
      url: "customuri:/" + info.linkUrl
    },
    function(newTab) {
      setTimeout(function() {
        chrome.tabs.remove(newTab.id);
     }, 250);
    }
  );
}

chrome.contextMenus.create({
  "title": "Open this link with a custom URI", 
  "contexts":["link"],
  "onclick": handleClick
});

Here is a pastebin of the same: https://pastebin.com/fuYFjSHN

What is the expected behavior?
It should open up the prompt to "Is it ok to open this link in CustomAppNameHere?" while also closing the empty tab that was used to get there.

What went wrong?
Leave an empty tab there, and all attempts to close that tab autmoatically failed.

Did this work before? No
