Scrolling wont stop after 'Failed to Download' window opens

[Vortex]

There's a minor bug that happens when you're scrolling up or down the list of books in a library, at the same time as the dialog box opens that says: "Failed To Download Metadata & Covers For..." .
It causes the scrolling to keep going after you stop, it just keeps scrolling until it reaches the bottom or top (depending on which way you were scrolling). I dont know if this is a known bug or not but it's been annoying me for a while so thought I'd report it.
