debt: 2 failing Firefox playwright E2E tests after npm packages

[megahirt]

Curiously, after updating our npm dependencies there are two Firefox playwright E2E tests that consistently fail:

2 failed
[firefox] › editor/editor.entries.spec.ts:207:7 › Editor entries › Create new word, modify new word, autosaves changes, new word visible in editor and list
[firefox] › editor/editor.pictures.spec.ts:53:7 › Editor pictures › Showing and hiding captions
17 passed (3.1m)

Looks like this might be either a Playwright bug or a Firefox bug, as someone else is experiencing the same issue: https://www.github.com/microsoft/playwright/issues/29614
