Duplicate Manager: the first double click on a thumb does not switch to this image

Is there an existing issue for this?

• I checked and did not find my issue in the already reported ones

Describe the bug

With 5.6.1 and before, if in duplicate manager you double click on a thumb, this image is loaded for editing. With current master, the first double click has no effect, the second one switches the image.

Say you have an image with two duplicates (A and B).

• from lighttable open, say, A
• A is shown on the canvas
• in duplicate manager, double click on B -> nothing happens
• double click on B again -> image switches to B
• double click on A -> nothing happens
• double click on A again -> image switches to A
  ... and so on.

Note: if, in the above scenario, you substitute the first double click on a thumb by a single click, the next double click switches the image. Consequently, a triple click also immediately switches (which is my current work around).

Start by reproducing the issue in darktable's duplicate manager using the A/B sequence described in the report, then trace the thumbnail click and double-click handling. Done means the first double click on a different duplicate switches to that image, without requiring a second click; verify the existing single-click and triple-click behavior as well.
