Okay.
Setting: Floating [ON] / Floating Navigation [ON]

When I press the arrow button of Floating Navigation, the back to top button does not work.
After that, the screen does not scroll and does not change even when you press the arrow button.
When you press the Arrow button, an ID that starts with #~ appears after the URL, which seems to be the reason.
If you open and press the Floating menu instead of the arrow button, the #string will not be created. back to top also works fine.
