fix: Prevent the feedback element to be clicked

[brunosabot]

Context

Trying to solve #533, I end up seeing that the feedback element became clickable and prevent the buttons to be "double_clicked"

What did I do?

• I add a pointer-event: none css on the feedback element
• I clean a bit doubleTapTimeout to use the constant from the top of the file
• I reset the timeout variable when cleared

Next step

Check with #533 if it solves the issue.
