We were building an app to sign up for a toll road that shipped electronic tags to the users, circa 2008.

  <input name="tag" id="tag"
this failed in IE with very strange results. Took a long time to realize we had hit a browser bug and change it to:

  <input name="tagx" id="tagx"
which worked fine.
