The reason for this was that the search for an expression was slightly left-biased: When on the edge between two tokens, it first looked at all ancestors of the left token and then of the right token. Instead merge the ancestors in ascending order, so that we get the smaller of the two possible expressions. This might seem rather inconsequential, but emacs-lsp's sideline requests hover for the beginning of each word in the current line, so it tends to hit this a lot :smile: Actually, as I think about this now, another solution might be just making hover right-biased, since if I'm hovering a certain character I really mean that character and not the one to its left...
