[orca-list] Can't Uncheck Speak Description in Ubuntu 19.10

[Brandon Tyson <brandongold98 gmail com>]

Hello,

In Ubuntu Mate 19.10 (Eoan Ermine) using Orca 3.31.4, I can't uncheck
speak description on Orca's speech tab.

Steps to Reproduce:
1. In Ubuntu Mate 19.10 turn on Orca with alt+super+s.
2. Go to preferences, with orca+space.
3. Go to the speech tab and uncheck the "Speak Description" option.
4. Press OK.
Expected result: After pressing OK and going back to the preferences
window, speak description should remain unchecked and thus the setting
should take effect.
Actual result: The setting gets reverted and never takes effect.
This works fine on Debian Testing (Buster) running 3.30.1 of Orca.

Thank you very much for your time and I look forward to any assistance
you are willing to provide.

Sincerely,

Brandon Tyson
