Today I found my mozilla engine based browser (Mozilla Firefox 52.2.0 (32-bit)1) left me with some strange (image) rendering quirks at the Tavern on the Meta chatroom:
As the title says there are only alternate texts for some images rendered, but that screws up the whole
<span> (I dunno really) rendering.
I suspect it might have something to do with the "not blocking insecure passive content" as described here:
Though I didn't find a way to fix that, or what might be the reason (most of the image URL's2 are using https transports anyway).
Is that a known bug? I never experienced that until today.
At the dev console I see:
Use of getPreventDefault() is deprecated. Use defaultPrevented instead.
1I'm using the Tor browser for various reasons TBH.
2Well, I didn't really check all of them, just some probes.
