[Mainsite] Showing unavailable chapters enables Read button

[DokterKaj]

If a title has no available chapters and the "Show unavailable chapters" checkbox gets ticked, the Read button ("Start/Continue Reading" on desktop, "Read" on mobile) becomes enabled even though it should still be disabled since none of the chapters can be read.
Strangely, this doesn't occur only when you're logged out on mobile. It occurs when you're logged in on desktop or mobile and when you're logged out on desktop.
I have tested this on Firefox desktop, Firefox Android, and Chrome Android.

EDIT: It should be noted that clicking the enabled Read button doesn't do anything.
