Smileys missing with chrome, OK with FF

Hi,

When using chromium/Brave/Chrome to connect to our jitsi instance, or even https://meet.jit.si, the smileys in the chat area are not all correctly displayed.

A screenshot using Brave Version 1.8.86 Chromium: 81.0.4044.129 (Official Build) (64-bit):

And it’s the same with chrome and chromium.

Firefox 75.0 (64 bits) shows something better, see another screenshot:

Since browsers of the chromium family are recommended, it’s a little upsetting.

I did not find where these smileys are stored, and I don’t know what to do to improve their display in Brave…

Anyone can help?
