I use several Desktop Spaces. I’ve linked an email and a Drafts draft.
When I try to switch to the Drafts entry and Drafts is not on the Desktop Space where Mail resides, Drafts is only activated (in the Menu bar) but the text not displayed or the Desktop Space changed to the one with Drafts.
A workaround I found is to set Drafts’ option to “All Desktops”. However, I’d like also to use the option “None” or “This Desktop”.
I haven’t tried if this a general bug or only related to Drafts but I assume it is a general bug.
