Sync blocking Brave browser to load DevTools script ignore list?

Description of the issue:
DevTools allow scripts to be blackboxed/ignored so they will never open in the debugger even when you choose to step into one of its functions.

Brave v1.34.80, however, appears to be clearing these settings each time I launch. How can they be persisted?

Steps to Reproduce (add as many as necessary): 1. 2. 3.
Before closing Brave, I will add an item here:

And after restarting Brave, it is gone:

Reproduces how often:
100% of the time on all machines.

Brave Version(See the About Brave page in the main menu):
Brave v1.34.80

Type of devices currently running on the Sync chain in question:
Machines have sync off; Have tried sync with no change in behavior

Additional Information:
The reason I have posted in the forum is because I notice the settings are being persisted in the %appdata%\Local\BraveSoftware\Brave-Browser\User Data\Default\Preferences file under the key “synced_preferences_sync_disabled”
