Last line highlighting after undo operation in SciTE

[MrCreatoR <mscreator@…>]

Just type this single line (without any other empty lines) in the SciTE editor:

Exit

and now put the cursor at the end and type something quickly (for example: Test), then undo the changes (Ctrl + Z). You will see that the keyword is not highlighted anymore as it should.

BTW:
It's not only keywords, it's also functions, udfs, macros, preprocessors, and special keywords.

I get the same behaviour in the lexers for ".bat" and ".c" files so assume the Scite Editor doesn't request the Scintilla Lexer to update the Syntax colouring.
So assuming a SciTE bug which I will not be working on.
