Browser scope is not saved / updated

[ppseprus]

Current behaviour:
I first tried to set my browser scope through the setting.json, however, it did not have anny effect. I tried to then set it in the workspace settings. Also nothing.
When I use the shortcur (alt + b) and type e.g. "safari 10, ie 6-8" I can see that the scope os limited to Safari and IE, however, this setting is not saved in either of the above places (global or workspace settings).
When I restart VSC, the browser scope is yet again not set.

Expected behaviour:
Browser scope is saved in either of the settings and remains saed after I restart VSC.
