It seems that with commit b50cd5317e76b3abe44c56ae86e44c04bebce7bf the first instance of a group contained in an extend appeared. Since then the Wireshark dissector generator fails on this code found in specs/cat021/cat-2.6.ast

remark
Bits 7/2 contain the total number of bit corrections applied to all
Extended Squitter Messages used for the composition of this
Category 021 Target Report (regardless of the ages of the Extended
Squitter messages). More details on the techniques applied for error
correction can be found in EUROCAE ED-102B/RTCA DO-260C
[11], Appendix I “Extended Squitter Enhanced Reception
Techniques”.
It seems to raise an exception in get_bit_size() when working on '# iterate over items, reinsert FX bits' in handle_variation() while trying to determine the size of the 'group', which does not have one.
With the Wireshark 4.0 release expected later this month, this issue needs resolution to get the updates in the protocols added in that release.
