that seems like a bug. please file a report against qt, component build
system.

yeah, it's broken. the issues that prevented me from fixing it were
fixed meanwhile, so i should give it another try ...

for the time being, you can use the german translation as a template, as
it's being kept up to date (the one for 6.9 is pending on gerrit, but
you seem to want to target 6.7 anyway). use `lupdate foo_qt6_de.ts -xts
foo_qt5_lg.ts -ts foo_qt6_lg.ts` to transplant your qt5 translations
into it (at least i think this command should work ...).
