Force please

@SebastianKrupinski in #58225 (comment) you state it needs

This will require this:

#58526

Then this:

#60234

While #58526 is merged, #60234 is still in draft state (!)

[SebastianKrupinski]

While #58526 is merged

• this is only merged in master which was 34, the back port for 33 was never triggered because this PR needs to be merged first.

#60234 is still in draft state (!)

• this is in a draft state because the back port was triggered before this PR and fix(theming): Fix favicon and touchicon ratios #58526 was merged. So once this PR and fix(theming): Fix favicon and touchicon ratios #58526 are merged... [stable33] fix(theming): fix broken custom images introduced by #58224 #60234 will need to be reapplied on top of those.
