Summary
Adds a unit test that verifies table selection is properly cleaned up when the mouse leaves the browser window during a drag operation and re-enters with
buttons=0(button state lost).Also fixes the PointerEvent test polyfill to use nullish coalescing (
??) instead of OR (||) sobuttons: 0can be passed correctly.Closes #5928
Test Plan
pnpm run test-unit packages/lexical-table/src/__tests__/unit/LexicalTableMobileSelection.test.tsx- all 6 tests pass
