I have a question related to this one: biblatex-verbose: edition as superscript in front of year
I'm using biblatex-musuos and that solution works for it as well, but only for normal entries. Child entries using crossref do not get a superscript. What confuses me is that it works for both parent and child in biblatex-verbose. But musuos and verbose both require the authortitle style and I can't tell what musuos does differently that might prevent this from working. The incollection-bibliography driver in musuos looks essentially the same as the standard one and I don't know what else could influence this. What can I do to make it work in musuos? (My apologies if I'm missing something super obvious.)
This is the result I get using musuos. If you change the style in the MWE to verbose it looks like it's supposed to, with superscript before both years.
MWE (minor changes compared to linked question marked with comments):

location+date: In some musicological styles, the publisher is omitted in any case, and only location and date are used. But inmusuosthis doesn't seem like an explanation, sincecollectionstill uses the publisher, butincollectiondoes not. So I'm not sure either. Perhaps an inconsistency in the style? – MrBubbles May 05 '22 at 09:29publisher+location+dateinstead oflocation+date. If thepublisheris not desired, I'd probably have redefinedpublisher+location+dateto drop thepublisher. The current situation is a bit inconsistent in any case. (As can be seen in the example if you add apublisher.) – moewe May 05 '22 at 15:26
