Word Replacements: entering a string with HTML will reset all replacements
How to reproduce:
- On a single language site, go to Administer > Customize data and screen > Word Replacements
- Enter a few replacements, it doesn't matter if they are valid.
- Save, so far so good.
Then add a new replacement with html:
<p>test</p>, and click save.
Result: word replacements table will be completely empty.
