Looks like we should have done this before merging OOUI 0.22.0. :-(

So what was marked as deprecating was actually a breaking change? Then we either need to revert or do a patch release of ooui.

Inspectors throw exceptions if I press 'cancel' - that's too broken to not revert.

Something is pretty broken in VE here… somehow ve.ui.WindowManager#closeWindow is calling itself recursively, breaking some assumptions in OOjs UI code.

That said, OOjs UI is also broken. Trying to close a window that is already being closed should fail gracefully, not cause exceptions.

Alright, OOjs UI v0.22.0 really is broken. The new code has a couple of bugs we missed, mostly related to closing windows. There's nothing wrong with the WindowInstance concept (and nothing we should need to fix in VE), they are just bugs.

I'll be submitting a few patches. We should probably release v0.22.1 today (although I'd be fine with applying local patches in MediaWiki and VisualEditor too).

This fixes the exception when closing an inspector.

I don't think the problem here was causing any visible issues, but it's still broken. I noticed this when writing the previous patch.

This fixes a test failure that James sneakily worked around with https://gerrit.wikimedia.org/r/#/c/356316/3/tests/ui/dialogs/ve.ui.FindAndReplaceDialog.test.js.

These three patches do not affect VE specifically, but they are also fixing bugs caused by the same changes.

There are enough other consumers of OOUI windows that I wouldn't be happy with just patching VE+MWcore.
