Keepassxc-browser: Browser extension: RAM leak (+1GB) and CPU hogging (100%)

[maniqui]

When launching the browser, KeePassXC-Browser extension consumes 22MB of RAM and almost no CPU.
After a few hours running, the RAM consumption goes up to more than 1GB (and it would have kept raising if I didn't killed the extension) and the CPU usage is 100%.

See picture:

Expected Behavior

The extension should not leak memory nor hog 100% of CPU.

I found the function where this happens. Fixing ASAP.

Found another bug related to this. I couldn't get the exact point where this memory leak happens but it's clear that it's a tab object.

The exact point this happens is https://github.com/keepassxreboot/keepassxc-browser/blob/develop/keepassxc-browser/keepassxc-browser.js#L1172. If everything else is commented out but the sendMessage is left, the objects still leak. It's probably related to event.js's kpxcEvent.invoke. I'll do more testing when I have the time.

Btw, I noticed that with Chrome/Chromium setting the icon leaks some stuff. This is a bug inside their browser implementation. Haven't found a better way to change the icon dynamically.
