8230809: HTMLEditor formatting lost when selecting all (CTRL-A)

[aghaisas]

Bug : https://bugs.openjdk.java.net/browse/JDK-8230809

Root Cause :
Turned out to be a simpler issue than thought.
Atomicity check was missed while updating toolbar state (which in turn updates styles).

Fix :
Added the missed atomicity check at two places that handle text selection using keyboard keys.

Testing :
Added two system test cases. They fail without this fix and pass with it.
