ILE: Increasing the visibility of selected works

[QuantuM410]

Issue: #8659

Proposed Solution

I think it would be better to stick with just sliding up the selection above the ILE blue bar on clicking "N works selected". It would allow the selected works to appear above the blue bar upon click and immediate visibility of the selected works. This implementation would not mess with the drag and drop functionality as mentioned here #8659 (comment) by @cdrini.
Other than that we can also choose to go with an implementation of a drawer or a menu like bulktagger but I am not sure if that won't interfere with the drag and drop functionality. If @cdrini or someone can verify the working of setDragImage API in a drawer or menu, this can be a better solution :). As its been mentioned here #8659 (comment) that

I implemented the visibility issue by shifting the selected works above the ile toolbar and made the works clickable as of now. The toggling of "N works selected" have been added to hide or display the selected works. Any review would be appreciated, so I can make a PR! :)

Thanks @QuantuM410, and sorry for the delay. I'm going to remove the click listeners and keep the style changes.

Drag and drop feature seems to be working on Firefox, but I can't find documentation on this feature to confirm.
