Shift Delete fails to permanently delete items & shift key sometimes sticks ON

Tested in 0.4.15-dev-3238-ge6fd41d and 0.4.15-dev-3120-g0233bb7.
Video is attached. Log has nothing specific to indicate any problems.

1) Click and Drag file to Recycle Bin NOT holding shift when released
   Expected to see "... send'file' to the Recycle Bin?"
   Results are seen as expected.
   Select "No"
2) Click and Drag File to Recycle Bin holding shift when released.
   Expect to see "...want to delete 'file'?"
   Results are seen as expected.
   Select "No"
3) Click and Drag File to Recycle Bin NOT holding shift when released
   Expected to see "... send'xxx' to the Recycle Bin?"
   Results are "...want to delete 'file'?" ("shift" key not released?)
   Select "No"
4) Right click on File and select "Delete" while NOT holding the shift key
   Expected to see "... send'file' to the Recycle Bin?"
   Results are seen as expected.
   Select "No"
5) Right Click on File and select "Delete" while holding the shift key
   Expect to see "...want to delete 'file'?"
   Results are "... send'xxx' to the Recycle Bin?" ("shift" key ignored?)
   Select "No"
6) Right Click on File and Select "Delete" while NOT holding the shift key
   Expected to see "... send'file' to the Recycle Bin?"
   Results are seen as expected.
   Select "No"

The above applies to not only 'files', but multiple files, folders and multiple folders.

This is an old issue that Giannis fixed in SVN r69647.
But this regressed in SVN r72512 and has been a problem since.

Patch shift_delete_fix10.patchis attached. I will create a PR soon.
