Copying and pasting a really long data URI into bugzilla's textarea comment field causing a several seconds long hang.

Selecting it with CTRL+A also causes a several seconds long hang.

STR:
1. Download attached file.
2. Copy file's contents to your clipboard.
3. Paste in bugzilla's comment field.
4. Observe hang.

Expected results:
Firefox magically doesn't hang. Possibly by not trying to spellcheck data URIs or some such.
We're spending all of our time in WordSplitState::FindSpecialWord.
