do you have an efidisk? if not, this setting cannot be saved...
the following steps work here:
* create vm with ovmf and efidisk

there is no "proxmox's implementation of ovmf"
our package simply compiles the upstream version and changes the logo
aside from that, the instruction mentions a patched version of
ovmf, so you do not even use our package?
also, using a recent ubuntu live cd (19.10) i cannot reproduce that
since the live cd changes the resolution correctly and
you can select many resolutions there (working)
so i rather believe that this is a limitation/bug of macos's interaction
