so i think it was an issue only on safari
i guess it had to do with this css:
html, body{
overscroll-behavior-y: none;
}
usually this css shouldn't disable scrolling :O
but maybe this is an issue in safari at the moment
i changed things so this css is only enabled on pages with covers, thats what it was meant for only anyways
will be changed with the next update.
but not sure if it was really the reason for the bug yet
