VO doesn't work properly with home/end keyboard shortcuts

Test device
MacBook Air (m1 chip)

Operating System

Browser
safari

Problem description
phetsims/qa#702

When VO is on, the home/end (fn + left/right arrow) keys don't work properly. Instead of changing the mass values to min/max, the VO focus moves off of the vertical spinner. This is also seen in the published sim.

Steps to reproduce

1. Turn on VO
2. Tab to either vertical spinner
3. On a Mac, use fn + right arrow and fn + left arrow to try and change values to 10 and 1. Then use arrow keys to change the values in smaller increments. You will see that the values change because the focus highlight is still on the spinner but VO focus is no longer on that particular spinner.
