Spell-check wrong-dirty text upon showing context menu.

This makes for a better user experience when the idle jobs
haven't yet ran on some text to check for spelling.
This can happen when the user is on a device with insufficient
compute power and/or other idle jobs with higher-priority
take precedence.

This change leap-frogs the spell-checking idle job when the
user might already know they mistyped a word and look for a
quick fix via the context menu.
