Comment 7 for bug 1946022

So I just checked if the changes made to the GUI synchronized with the configuration file: ~/.config/qpdfview/qpdfview.conf. According to your guidelines. And yes, synchronize, if I switch to 30000 ms (30 s) in the GUI, in the configuration file is also changed successfully, in the "hightlightDuration" key. Now the issue is the behavior, which remains unchanged, that is, I can put the personalized value that is, however, the duration will always be 5000 ms (5 s). I barely pass the mouse on top of my highlight and disappear. So I want to change to a larger value like 30000 ms or 60000 ms. Unfortunately, no matter what value I define and is always maintained the same behavior.
