Prefix with theme name working vs not working

[UdayHyma]

Describe the bug
If I have the dark theme selected but want to export styles for the light theme with the export option Prefix styles with active theme name enabled, the plugin instead exports styles with Ignore first part of token name. It seems to be the case that a user has to select the the set and theme 2x before being able to export it correctly with the Prefix styles with active theme name option enabled.

To Reproduce
Steps to reproduce the behavior:

1. Have two sets also setup as themes - same theme-group
2. Select Set B in the plugin's main view
3. Enable the Prefix styles with active theme name option
4. Select the appropriate style options
5. In the themes screen, instead select Set A for export
6. Export styles
7. See error

Expected behavior
I don't think the user should have to select the set first then proceed to select the same set again but in the themes screen to export as styles with the Prefix styles with active theme name option enabled. Regardless of which set is selected, the user should be able to export the any theme that is selected in the final export screen.

@UdayHyma @rbosker @keeganedwin , isn't this consistent with the expected behaviour that only those styles shall be exported when the corresponding set is active:

@akshay-gupta7 > that is correct, the difference is that we now have 2 places where we can enable sets: the plugin and the export modal. I expect that if I enable a set in the export view, that just works like the set is active in the plugin view.
