rust backgroup ugly

[greyireland]

Please provide as much information as possible, usually I need these information to actually start working on an issue, so try to fill as much of these as possible

Sample code

want this

Remove the font blue background, or dim the font background. The blue background is too conspicuous and interferes with the core code flow

[greyireland]

I hope the blue background will be consistent with the color of the annotation

[greyireland]

If you can tell me how to modify it to achieve this goal, it's OK

This should be fixed in 2.3.0.
