Repro steps:

• Go to feedback.minecraft.net
• Hover over categories and select Add Feedback
• Enter the following text into the title, "Fix ore generation that was broken by underground biome introduction" (this likely happens with multiple types of text field entry)
• Click in the Details box to start adding details
  • Alternately, wait for a few seconds

Expected behavior:

• Allow the user to enter the remainder of the details of their feedback and submit it

Observed behavior:

• The details field disappears, and is replaced by a series of "similar posts", none of which have anything to do with the text typed into the feedback title above, with NO way of getting the fields back to add new feedback.

I guess this is one way of keeping people from submitting feedback about features Mojang doesn't want to implement, but it's a little heavy handed, don't you think? Added screenshots of the bug in action.
