Window is out of focus when escaping clipboard

The window previously focused becomes out of focus when pressing escape key or deleting clipboard without selecting any texts.

Are there any settings to keep the window focused?

It annoys me I have to focus on specific window manually every time

Did you maybe disable the float on top setting?

Thank you for the reply.
Yes, it worked as expected when checking the option.

But I suppose the key bindings you can use on clipboard are affected by the window previously focused.

There are some keys I’d like to use on clipboard with any windows/applications.

I’ve been dealing with it by applying those keys to BetterTouchTool itself and unchecking the option.

Is it possible to work it out?
I’m sorry, this might be a different problem…
