📝 Description

When New Tab is set to Custom, dragging the suggestions list hides the keyboard and unintentionally cancels URL bar editing, which closes the suggestions abruptly
This change skips the keyboard hide auto cancel while suggestions are visible aligning behaviour with Firefox Home/Blank.

Test plan

• Setup:
  • Settings → General → New Tab → Custom, URL: https://www.google.com
  • Address bar position: verify both Top and Bottom
• Custom New Tab
  • Type “fir”; drag/bounce suggestions → suggestions stays
  • Tap Cancel while dragging → overlay closes.
  • Tap a suggestion → loads and overlay closes.
  • Press Return → submits and closes.
  • Rotate mid-scroll; start/stop dictation → no unintended dismiss.
• Firefox Home & Blank: drag keeps suggestions; Cancel still dismisses.
• Private: unchanged (no suggestions until turned on manually)

@ananyashreesharma We're currently exploring a simpler fix, and there are some internal discussions underway about the expected behavior. We're waiting on clarification, so it might take a few more days before we can move forward.
