RTL styles of old and new template are broken in IE7.
Both templates:
* <del>edit toolbar pickers don't work (or at least they don't show up)</del>
* media manager's (fullscreen) swipe diff (
FS#2433)
Old template:
* media manager (fullscreen) makes a huge horizontal scrollbar appear
* <del>media manager's (fullscreen) namespace tree at the left is jumbled up</del>
New template:
* <del>the page tools work, but create a weird and annoying artefact</del>
* the user and site tools are not aligned with the left-hand side
* a huge horizontal scrollbar is always present
