Closes #2232

* Fixed several of the issues and nits from PR:

* 'Scrollable Header' (see above comment to why this is necessary) but I did increase the max-height from 35% to 50%.
* Fixed header and 'X' button vertical alignment

* Temporary stack margin fix

* Move "N errors" to the top

* Tweaked overlay styles

* Tweaked pre-style

* Clicked to background overlay dismiss
