Bitrate setting is not saved when YUV 4:4:4 is enabled

[KWottrich]

Describe the bug
When using a build of the client that has YUV 4:4:4 enabled, going into the settings and changing the Video bitrate setting doesn't do anything. Dragging the slider and then closing and reopening settings resets the slider right back to the default for the resolution/FPS. In my case, that's 65 Mbps for 1920x1200@120 FPS. Disabling YUV 4:4:4 makes this issue go away

Steps to reproduce
Build from the latest master branch, with the changes merged in #1282. Enable "Enable YUV 4:4:4 (Experimental)" under Advanced Settings. Attempt to adjust video bitrate.

I will have a look.

The value is getting saved, but the slider is reset to default when the options page reopened.
Will open PR with a fix shortly.
