I read a lot, late in the evening, up to midnight.
As such, I use Dark Theme, which is more relaxing to the eyes.

Up until iOS10 update, the Define option (called now Look Up, but I don't mind), would open a darkish colored pop-up window, with the size approximate of the number of words contained in the answer). I'd read the definitions and then, with a simple touch of the finger on the screen would close it.

Now it's different and completely annoying!
Instead, it pops up a white window (with dark theme on), with static size (roughly 35% on my iPad screen), regardless if the definition is only one line long. And I can't close it by touching the screen with my finger - now I am forced to press "Done" command, in its top right corner.

I posted this on Apple forums, but I don't think they ever read that. Submited a ticket, but god knows if they actually pay attention to that.
Has anyone else enountered this issue and found a solution?

Thanks in advance for your time!
