I didn't play DAI, so if her husband was a dwarf, how did she see him in the Fade? Or was it funny because it was fake and that's how she knew?
On the edit, was it not obvious? It's hard to tell what my first impression would be without you telling me, but from the pictures I saw when I looked up the name, I totally see it.
What River said above. Also, Maevaris as drawn in the comics, and also in the Trespasser Tevinter slide with Dorian, is presented as a woman 100%. There was a scene in the comics where her dress/robes were ripped in the chest area and you can see that there are no breasts there. That was sort of the reveal for the character. Reading along in the comic is was one of those things like, "Uh... OH!" and then you understand and move on. Because there was so much going on, and the comic was not about Mae, it's not touched on as an issue, so the reader is left to come away with their own thoughts, positive, negative, or neutral, as the case may be.
Since you already knew, your perception of her was a bit biased toward "seeing it." I can assure you that while reading the comic on release it was a complete surprise to me. In every previous panel I saw her in I thought she was a cisgender woman because she was presented that way -- this is my own perception, of course -- and I believe the artist intended it to be so.

A game depiction would be quite interesting. It would all depend on the voice -- I thought Jennifer Hale's Krem was fantastic -- and what kind of clothes the devs are able to get her in. Her comic clothing was fantastic and I'd love to see how that would work out in a game. (Going shopping with her and Dorian would be a blast...)
