I was looking at the failure "Windows 11 x64 22H2 WebRender Shippable - X-mix(X4)” and it is a new(ish) permafail since April 9. The first time it starts failing (same errors as we have today) could be related to an m-c change done that same day.

it looks like the test_close.js is skipped for m-c treeherder runs, because of dom/webtransport/test/xpcshell/xpcshell.toml. so why isn't it skipped for us? what version of windows 11 do we have in our CI? If it's different from os_version == '11.26100' then is there a common way that we overwrite elements of m-c tests (in this case, to match if our windows version is different from m-c's)?

thanks for filing this- and sorry this turned into an issue for you. You made my job easy to figure this out.

In January we migrated our windows tests from the win11-64-2009 machines to win11-64-24h2 (see bug 1936396). the machines on comm-central are running the win11-64-2009 image which is os_version=='11.2009'.

I found this by looking at a comm-central push and in the mochitest tasks we print out all of the variables (i.e. this log - search for os_version).

2 choices here:

1. update the conditions to skip on 2009. For this specific test it would be in the [DEFAULT] section at the top.
2. migrate to the 24h2 version of windows. This is the windows 11 Oct 2024 major update.
