Comment (by flixos90):

 In [changeset:"57155" 57155]:
 {{{
 #!CommitTicketReference repository="" revision="57155"
 Themes: Clean up inactive themes' theme mods from being autoloaded as part
 of upcoming 6.5 upgrade routine.

 Alongside [57153], this reduces unnecessarily autoloaded data from
 inactive themes, which can contribute to slow database performance as part
 of excessive autoloading. This changeset specifically resolves the issue
 for existing sites.

 Props mukesh27, joemcgill, swissspidy, westonruter, flixos90.
 Fixes #59975.
 See #39537.
