behavior is required, or no licenses should be saved use the

WARNING and NOTE: some servers do improperly send orders that weren't negotiated,
for such cases the new command line option /relax-order-checks was added to
disable the strict order checking. If connecting to xrdp the options
/relax-order-checks *and* +glyph-cache are required. (gh#/FreeRDP/FreeRDP#4926)
