I confirmed that master GStreamer doesn't reproduce the bug, while 1.16.2. I bisected GStreamer between these two points and found the commit that fixes the issue.

commit 7e2073000a82a1e3361ac806ea698d2cf7ff0a30 (HEAD, refs/bisect/fixed)

    glbasefilter: add support for changing the display

    Each element will remove its usage of the old display and context and
    try to retrieve a new GL context.

Víctor is trying to remove redundant context setting which could also make this a non-issue for WebKit under currently released GStreamer: https://bugs.webkit.org/show_bug.cgi?id=213029

If that doesn't work, we could try to backport this patch to our flatpak GStreamer so that we get rid of one big source of flaky crashes when running multimedia tests.
