Firefox Bug: Absolute Position + Arrow Navigation

Steps to reproduce:

  1. Click into the first (normal) field below
  2. Try pressing Down Arrow to navigate to the absolutely positioned field at the bottom
  3. Notice: In Firefox, the cursor does NOT move to the absolutely positioned field
  4. Now try Right Arrow repeatedly - it WILL navigate to the absolute field

Expected behavior: Up/Down arrows should navigate to absolutely positioned elements (works in Chrome/Safari)

Actual behavior: Only Left/Right arrows work for absolutely positioned elements in Firefox

First field (normal positioning)
Second field (normal positioning)
Absolutely positioned field - try reaching me with arrow keys!
Current focus: Check the console or look for the blue dashed border
