What

The plugin sandbox protocol adds ui.press to its operation list and dispatch table, with the worker counting presses in flight and declining to go idle while any are outstanding. The layout map gives Button block display and the plugin JSX runtime defines h. The fs.ancestors file operation landed in the same change.

Evidence

"ui.press"

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
