Comment (by jonsurrell):

 I did some testing with CSS concat as well. The same issue is not a
 concern because CSS does not have line-based comments so they always
 terminate.

 However, separate inline styles can still be concatenated with multiple
 `sourceURL` so it seems best to disable there as well.

 An approach to disable the comments when concatenating scripts/styles
 seems to fix the issues and removes the problem of multiple `sourceURL`
 comments in a single inline script/style.

 Some descriptive `sourceURL` comment could be added to concatenated
 scripts, but with efforts like #57548 it doesn't seem worth investing more
 effort to better support concatenation.
