Link to original bug (#14372)

Description

As it was discussed on IRC, the following functionality is needed in xkbcomp

If some XKB option is using some symbols in group 1, they should be propagated to all groups present in the configuration. Something like

! option = symbols og:abc = symfile(v):all // equal to og:abc = symfile(v):1 + symfile(v):2 + ... till the last group
