I saw this issue on all sites (excepting (Meta) StackOverflow, and maybe others). Even after Geoff's fix, this still happens in the latest build (
rev 2014.6.12.1658) on Graphic Design (but not here on Meta SE). The following screen shot is taken from graphic design site:
Steps to reproduce:
- Open /questions/ask
- Type enough content into the body to remove the margin between the preview and footer.
- Start typing a tag - if there's more than one row of autocomplete suggestions, the list will get cut off by the footer.
