I mean the code under editor/ in the Gecko source tree, which handles the backend of editors for both Firefox and Thunderbird. Thunderbird's composer uses the Gecko editor for composing mail, but also has its own code that it puts on top, so the post you link to may be referring to that. This bug is in the editor itself, not the Thunderbird-specific code. The two bugs you mentioned are Thunderbird-specific and not related to the editor (note "Product: Thunderbird", vs. this bug with "Product: Core").

That said, I actually haven't been paying much attention, and for all I know it could be someone has started working on editor again recently and I didn't notice. It doesn't seem so based on glancing at the log, but I didn't look at the commits in detail. If people are working on Thunderbird more, maybe they'll want to fix stuff in the editor too, since some high-profile Thunderbird bugs are really editor bugs. So we can still hope! :)
