Meta title of Kirby panel login page

Hi, I noticed, that meta title of is first shown as “Kirby Panel”, and then it changes to “Login | My site name”. And when I send link by Facebook messenger for example, it creates preview with “Kirby Panel” title:


Small thing, but it would be better to show “Login | My site name” from start, so that same preview is renreded, and so that client is not confused.
