Nemo crashes when selecting a folder, entering the folder

[Joshua Peisach]

[Impact]

 * When selecting a folder, then entering the folder and letting go of the folder, nemo, the file manager crashes.

 * This affects Ubuntu Cinnamon Remix and Ubuntu Budgie 20.04 & point releases

 * Simple fix of clearing the drag state

[Test Case]

 * To reproduce:
 * 1) Select a folder by left clicking. DO NOT LET GO OF THE BUTTON. KEEP HOLDING.
 * 2) Press 'Enter' to go into said folder.
 * 3) Now inside of the folder, let go of the mouse.
 * 4) Nemo will crash.

[Where problems could occur]

 * With this patch, it is possible that in some cases with dragging or icon changing, the drag state can be cleared when it shouldn't be.

 * Regression Potential: My main concern is drag state clearing when it shouldn't.

Status changed to 'Confirmed' because the bug affects multiple users.

[Mathew Hodson (mhodson)]

There's also a debdiff in bug 1861968 that contains this fix. It would be nice if there is a SRU for the changelog to mention each bug separately since they have separate test cases.

This is a duplicate, so we could a) wait for the other bug to be finished and mark it as fix released or b) mark it invalid
