Math arrows don't display with Beamer + xelatexmk + libertinus

I have beamer presentations I've been using for some years in class. This year, I discovered problems with the libertine package and following advice from this forum (Libertine package options with boldface and emphasis change numeric text) switched to libertinus. I now find that the various math arrows in my presentations fail to display.

Here's an MWE:

documentclassbeamer

usethemeWarsaw
%EDIT: inserting usefontthemeprofessional fonts here avoids the problem
usepackagelibertinus% works fine with libertine

begindocument
beginframeFrame name
beginitemize
item This is text.
item Rightarrow ($Rightarrow$)
enditemize
endframe
enddocument

I have determined that

replacing libertinus with libertine works fine; or

replacing xelatexmk with pdflatexmk works fine; or

replacing beamer with (say) article works fine.

It seems to be this particular combination.

xelatexmk was part of the MacTeX bistro and moved from the inactive engines folder. I do need XeLaTeX but perhaps this is no longer the way to do this?

I am curious as to the nature of the conflict....

EDIT: the suggestion by jfbu below does indeed solve my problem. From the beamer documentation regarding professionalfonts:

Beamer normally replaces certain character glyphs in mathematical text by more appropriate versions. .... If your professional font package takes care of this already, BeamerÃ¢Â€Â™s meddling should be switched off [by using usefontthemeprofessionalfonts].

I still wonder why the problem was introduced in this specific combination, however! (but can live in ignorance if need be :) )

EDIT #2: It would appear that the beamer package issue which I reported earlier today has already been addressed (Turn off font substitution for unicode-math) and should be implemented shortly. In effect, `beamers changes will be also suppressed when a unicode-math is loaded.

you may raise a ticket on the beamer issue tracker asking that the maintainer adds libertinus to the list of packages automatically triggering the equivalent of usefontthemeprofessionalfonts.
