Hello,
Thank you for your report. I have reproduced the described behavior and forwarded this ticket to our developers for research.
while your developers are at it let them also fix the problem with "(a|A)" kind of mask that only accepts capital 'A' as opposed to "[aA]"
I also have reproduced errors with | so our developers are already informed about them.
