it only affects MS VBA compatability

no, 'THIS' refers to the document running the macro and 'CURRENT' is the
'active' document. E.g. if a macro in foo.xls opens existing ba.xls,
'THIS' refers to foo.xls and CURRENT refers to ba.xls (after the
document is raised and opened and is still on top)

I haven't looked at that code in a long time so feel free to dive in
there, iirc basically 'THIS' is tracked in the uno context (VBA has a
custom uno context), CURRENT should be accessible as a UNO global
variable inserted in to 'application' StarBasic. It sounds like somehow
somewhere getCurrentDoc either is no longer searching for the correct
variable, or its no longer getting updated (used to be updated somewhere
in sfx2/.../objxstor.cxx (try searching for 'ThisComponent', it's bound
to be handled somewhere close to that)
There used to be some confusing (but necessary) indirection to handling
this e.g. because Libreoffice is a single application (and VBA support
was trying to support both Word & Excel) the code in objxstor.cxx needs
to find out which variable in StartBasic to update, in the case of a
Word document it would need to update StarBasic variable named
'ThisWordDoc' & for Excel 'ThisExcelDoc' variable (both can exist
simulateously if multiple documents xls/doc are open).  That is my
recollection how this used to work, it is possible imports from AOO code
have trampled/changed this possibly in an incompatible way

I think this would be a bad idea, getCurrentExcelDoc needs fixing to
return the topmost open Excel document
