[LH3403] Beta 13: Can't open/edit index card in corkboard mode

In corkboard mode, when you double click on an index card, it opens the parent folder in the editor and not the selected card.

To the devs: this issue is also discussed in this thread: [url]https://forum.literatureandlatte.com/t/lh3403-fixed-beta-13-corkboard-does-not-open-double-clicked-documents/44439/1]
