The preview images of pictures and web links in the discord forum do not load properly

Description

After I upgraded brave to version 1.48.158 Chromium: 110.0.5481.77 (official version) (arm64), The preview images of pictures and web links in the discord forum do not load properly.
I could only keep refreshing the browser page to load the image, and all of brave's security blocking features were turned on and off repeatedly, but to no avail. chrome with the same Chromium core does not have this problem.

It seems that Brave is sometimes not firing onload (or onerror) events for images. I made a test page that tries loading a broken image and ensures onerror is called. It fails for me (i.e. a timeout occurs instead of onerror event) in brave randomly in less than 100 attempts. No other browser fails (safari, chrome, chrome canary.) Discord probably checks the that images are available before displaying (I have an application that does similar check and this being broken causes images to not show.)

(Not sure if other events are not working: document.onload, etc)
