Bug#989332: libwebkit2gtk-4.0-37: May 30 upgrade for DSA-4923-1 broke the epiphany browser

[jose]

Package: libwebkit2gtk-4.0-37
Version: 2.32.1-1~deb10u1
Severity: important

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

Epiphany is based on libwebkit2. I access discord as a web app on epiphany.
To do so I go to the discord site [1] and click on "Open Discord
in your browser". 

Since the upgrade this systematically results in epiphany complaining 
with a "Something went wrong while displaying this page". I uninstalled
and purged both epiphany and webkitgtk2 files in my home dir (.cache,
.config, cookies, history) and reinstalled them. The bug still persists.

I don't have this issue when using chromium to open discord
in the same way.

Note that my system was up to date and this issue began immediately
after the DSA-4923-1 webkit2gtk security upgrade.
