Watching the trace didn't show anything too interesting. When it was supposed to scroll down and hit the file upload thing wait for the file picker to pop up, it seems to have gotten stuck in the description thing for 57 seconds. It's a bit weird.

Start with test/e2e/silos.e2e.ts at the failing test around line 349 and inspect test/e2e/utils.ts, especially chooseFile and addTlsCert around lines 233 and 262. Review the linked trace for the 57-second wait and reproduce the Firefox test. Done means the test reaches the file chooser reliably and verifies the scroll-to-name-field behavior without timing out.
