Issue:
Improve region dropdown display for BED regions
- [ ] Right now, BED regions with no descriptions appear twice in the dropdown, once as coordinates and once as "Region {coordinates}". This is confusing. We should not display dropdown options for these auto-generated descriptions.

- [ ] For regions with manually set descriptions, the coordinates and the description also appear as multiple entries in the dropdown, although they are semantically one region. We should display them as a single item if possible, maybe by using some sort of structured item support in the control, or maybe by concatenating them together and using the ability of the dropdown to display a label while holding a distinct value.

- [ ] There are `none:` entries in the region dropdown; they should be eliminated.

Improve Region Dropdown Selections
Use label system to display both path with region and description while ignoring description upon onChange
