These are two (relatively minor) display issues related to reviewing edits:
Tag Details Flyout
First, below you will see the tag mouseover details block "hiding" behind the overlay. Obviously, a display bug or oversight.
To reproduce: I got to this by clicking on the
edit(0) link under a question when a user without edit privileges suggested an edit.
Edited Text Change Hidden Behind Reject Reason Overlay
Second, this is less a "bug" than a conflict of the display of overlays.
Essentially, while rejecting an edit, if you're trying to review the edit itself, it may (often does) fall almost entirely behind the overlay, meaning if you need to refer back to the edit changes for your reasoning, you have to close the overlay, review, then reopen it. More annoying than anything. Not real sure how it could be resolved cleanly without changing the UI behavior.
To reproduce: I got to this after reviewing an
edit(0) under the question and then clicking on the
Reject button on that edit. (Note, I ended up improving the edit in the end.)
* Note: I've added a Feature Request tag for this, since I think this is a side-effect of the design of SOs user interface that I think could be improved. Let me know in the comments if you believe this should be separated into another question.
