Because when you open the Insert Special Character dialog you are stealing the focus away from whatever had it. Whatever had that focus last is the target for the Dialog whether it is a CodeView, the Find field or the Replace field or another field in a completely different Dialog.

That was the whole design from the beginning and after more than 10 years, I am not making ui changes without really good reasoning.

That is not changing.

Happy for suggestions for changes or new features and will consider them, but that in *no* way guarantees these changes or requests will ever be accepted into Sigil master.
