lv2:scalePoint lost when Run plugins in bridge mode

[jpka-]

I've noted that, for some plugins only, scale points are lost (replaced by just value ranges). But only when Run plugins in bridge mode experimental option enabled.
Example of affected plugin: Calf Tape simulator, parameter "Speed Simulation",
lv2:scalePoint [ rdfs:label "Slow"; rdf:value 0 ] ; lv2:scalePoint [ rdfs:label "Fast"; rdf:value 1 ] ;
are lost.
Other example: LSP Profiler Mono, parameter "RT Algorithm".
Example of not affected plugin: FluidR3_GM (looks like, it is not lv2, but SoundKits type).
Additionally: Even after bridge mode disable and restart, scale points detection work only adding new plugin(s) on empty rack. Using previously (with enabled bridge mode) saved '.carxp' file, scale points detection becomes non working even when all plugins are removed from rack and newly added; only restarting works.
Thanks.
