[BUG] Tabbing through Settings TUI changes boolean config values unexpectedly

What's Wrong?

When opening the /config panel, then tabbing through the pages/tabs with the TAB key, the currently selected option is changed (if it is a boolean).

What Should Happen?

The actual options in the content of the tabs should not be changed, as the "Settings" tip notes "(tab to cycle)". Only the Enter key should be used to change the boolean values.

Error Messages/Logs

Steps to Reproduce

1. Type /config to open the Settings panel
2. Note the value of the first item/boolean under the "Config" tab ("Auto-compact" currently)
3. Press the TAB key to switch to "Usage"
4. Press TAB to cycle to "Status"
5. Press TAB one more time to cycle back to "Config" and notice that the value of the first item/boolean has changed

• This happens if you tab _from_ any boolean option - when you tab 'away', it will change, plus switch to the next tab
