Overrides reset after publishing a library component update. Any way to prevent this?

I have a chip component in our design system library (1 text layer + 2 icon instances). When I make changes to it and publish, then accept the update in our project files, the text and icon overrides on all instances reset to the defaults. It's used in about 1,000 places.

Is there a way to prevent this, or to recover the overrides? Has anyone found a reliable workflow for updating components at this scale?
