1429750 - chrome.browserAction.setIcon flicker problem

Status: RESOLVED DUPLICATE of bug 1309347

(WebExtensions :: Untriaged, defect)

Description

[Jdanov-filebit]

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20180103231032

Steps to reproduce:

I ran into the following problem in chrome.browserAction.setIcon: 
1)Сreate a canvas
<canvas id="canv" width="27" height="27"></canvas>
<img src="1.png"/>
<img src="2.png"/>

2)Use it in JS as follows

var canv, canvContext;
var array_logo = [];

$(document).ready(function(){
	canv = document.getElementById('canv');
	canvContext = canv.getContext('2d');
	array_logo = document.getElementsByTagName('img'); 
});

function doAnimate() {
	canvContext.save();
	canvContext.clearRect(0, 0, canv.width, canv.height);
	canvContext.rotate(0.5*2*Math.PI);
	canvContext.drawImage(array_logo[0],-Math.floor(array_logo[0].width/2), -Math.floor(array_logo[0].height/2));
	canvContext.restore();
	chrome.browserAction.setIcon({imageData: canvContext.getImageData(0, 0, canv.width, canv.height)});
}

setInterval(function(){doAnimate();}, 10);


Actual results:

The extension icon is strongly flickering, or not at all, this behavior is only observed in Firefox, this code is correctly executed in the Chrome browser.


Expected results:

The extension icon should rotate around the axis without flickering and be visible

A similar issue was logged in bug 1309347. It seems that animated images for toolbar buttons are intentionally not supported (see bug 1309347 comment1).

Kris, can you please take a look at this? There are any updates regarding the animated images for toolbar buttons?
Also, can we close this issue as dupe of bug 1309347?
