This is a weird bug. I installed the new 1.0 with Extract extension and proceeded to work on a small project using the STYLE tags in a PHP file. For some reason Brackets would not save my edits between these tags. When I open and close Brackets after clicking Save, my edits are gone. I can edit in other areas of my page but not there.

I uninstalled Brackets and deleted all extensions and data and re-installed 1.0 with Extract. Same thing happened.

1.0 without Extract does not appear to be able to recreate this bug, so I'm left with assuming it's the Extract extension causing the problem.
