Short title

Infinite zoom on channel overview possible, showing overlapping channel numbers when zooming on a channel boundary

Describe the bug

Image

Steps to reproduce

  1. Open Channel overview, 5 or 6 GHz band view. 2.4 doesn't support zoom, so isn't affected.
  2. Repeatedly zoom in via the 2 finger zoom gesture.
  3. Observe that there's no (reasonable) zoom limit
  4. At some point, the channel numbers at the bottom start multiplying and overlapping, too

Expected behavior

Zoom should be restricted to some sane value, for example 20 MHz across the whole diagram width. I can't really think of a use case for higher zoom levels.

If you choose a finer limit, I suggest adding frequency values to the scale.
