Themes and terminal probe results moved onto objects, and huge theme files are skipped.
What's wrong with this entry?
Custom theme bases, user and plugin themes and the detected system theme now sit on one object with a change notifier, and terminal probe results (version query, synchronized output, background colour query, native cursor) sit on another that can be reset. User themes can also be listed and read in bulk through the storage backend, with paging capped and individual theme files over 256KB skipped. If that listing fails or hits its cap, already-loaded themes are kept instead of being cleared.
exceeds 256KB; skipping
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
