Clipboard PASTE AS=ASK trimming custom extensions

Hi there! o)

If I use..
Clipboard PASTE AS=ASK
and I enter "one.two.three.four.five" as the name for the file to paste as PNG.

The file will be named "one.two.three.four.png", the "five" will get lost.

Unexpected to me, what do you think?

Thank you! o)

Fixed in the next beta.
