Research direction
Start with the Monaco Editor playground link and reproduce the crash on Windows by enabling accessibilitySupport: 'on', selecting lines 322 to 336, and pressing Shift+Tab repeatedly. Trace the browser crash from this reproduction; done means the same sequence no longer crashes and normal behavior is preserved.
