Before committing Luca's patch I noticed the same problem with
BasicLinkLM. There the solution was to make BasicLinkLM extend
InlineLM, so that it implements InlineLevelLM.

All LMs which are a child of LineLM should implement
InlineLevelLM. LineLM collects all child LMs of a block which generate
inline areas, and indeed, generating inline areas should be synonym
with implementing InlineLevelLM. This presumes that there is a strict
separation between block and inline area generating LMs.

For RetrieveMarkerLM that separation is not so clear. I think it has
to implement InlineLevelLM, otherwise it cannot act as a child of
LineLM, at the penalty that you noticed.
