Having hyperlinking enabled causes extreme slowdown in the JavaScript editor whenever CTRL is pressed.  This is very annoying because most developers copy/paste with CTRL-C often while writing code but if the hyperlinking feature is enabled and you are working with a reasonably sized (couple hundred line+) JS file you are virtually guaranteed a couple second freeze even on a fast machine.  If JavaScript element hyperlinking is disabled, the slowdown goes away.

Reproducible: Always

Steps to Reproduce:
1. Get a reasonably sized (couple hundred line) JS file
2. Hit control while working in the document
3. Try to click somewhere in the file and notice Eclipse is frozen
4. Repeat with JavaScript Element hyperlinking disabled and no slowdown is present
