Reset styles doesn't work when style set via pushing to global styles

[dsas]

Description

When I use the new 'Push to Global Styles' button introduced in #46446, resetting styles afterwards behaves oddly - it doesn't seem to reset all properties.

What actually happens is that when 'Pushing' to Global Styles some local styles are moved to Global Styles, but some local styles are copied to Global Styles. This means that when resetting global styles, some local styles still remain.

It seems that link color gets moved, but background and text colours are copied. I've tested this on the post title, post excerpt and headings blocks.

Step-by-step reproduction instructions

1. Open up the site editor
2. Go to the archive page (just an example any will do)
3. Choose the Post Title block (just an example, post excerpt behaves the same way)
4. Set a background colour and a link colour. Note the preview update
5. In the settings sidebar press 'Advanced' and then 'Push to Global Styles'
6. Save
7. Note that the link colours in the sidebar have been reset but the background colour remains
8. Open the global styles sidebar, open the three dot menu and reset to defaults
9. Note that the link colour has been reset but not the background colour.
