Summary

Similar to the previous issue that I reported with edges (Polycut disables any face editing tool in modelling mode) , having two meshes that are not touching each other will make one of them unable to have its edges or vertices be selectable, as shown in the video:

Steps to Reproduce

Make two meshes and use merge on them
Paint polygroups
Polygroup edit and try to select the edges of both meshes

Expected Result

All edges are selectable

Observed Result

Edges and vertices of one of the two meshes will not be selectable
