Steps to reproduce the problem:
1. Start Chrome with pepperflash player
1. Go to http://www.bonth.nl/gynzy/chrome-bug/
2. Copy "BoldItalic" text from inputfield
3. Paste in new Word document (or Wordpad)
4. Instead of expected plain "BoldItalic" text you get <flashrichtext>formatting.

I can reproduce it on Windows & MacOs

What is the expected behavior?
If you copy text from an inputfield in Flash, I expect only text, without Flash formatting tags.

What went wrong?
Instead of "BoldItalic" I see
<flashrichtext version="1">  <textformat font="_sans" size="24" color="26316" bold="true" italic="false" underline="false" url="" target="" align="left" leftMargin="0" rightMargin="0" indent="0" leading="2" blockIndent="0" kerning="false" letterSpacing="0" display="block">(Bold)</textformat>  <textformat font="_sans" size="24" color="26316" bold="false" italic="true" underline="false" url="" target="" align="left" leftMargin="0" rightMargin="0" indent="0" leading="2" blockIndent="0" kerning="false" letterSpacing="0" display="block">(Italic)</textformat></flashrichtext>

Did this work before? No
