1596581 - While dragging an entry around, the cell over which the cursor is is highlighted in orange, but those highlights stay forever

Status: RESOLVED WORKSFORME

(Calendar :: Calendar Frontend, defect)

Steps to reproduce:

I'm using the Lightning extension for Thunderbird, Version 68.2.2 it says, the same version as my Thunderbird. I am using the Linux.

I create a new entry in the Lightning calendar, dragg it around a bit, over a few cells, and finally drop it over some cell.

Actual results:

While dragging the entry (but not yet having dropped it), the cell over which the mouse is at that moment is highlighted in orange, to indicate the cell where the entry will fall if I would let it drop at that moment. The problem is: those orange highlights aren't removed after I moved the mouse away, over another cell, still without dropping the entry. This way, more and more orange highlights on cells are created. And the worst thing is: those orange highlights even don't disappear after I drop the entry over some cell. They remain visible.

Expected results:

While I drag some entry around, only the one cell over which the cursor is at that very moment should get an orange highlight. After the entry is dropped, the highlight should disappear.

Perhaps it's important to mention that from the display options "Day / Week / Multiweek / Month", I choose "Month". The glitch also occurs when I choose "Multiweek". If I choose "Week", the error only affects those entries that are declared to be "All day Event"s. The entries in the part of the calendar that includes hours of the day are handled correctly.

danger, do you still experience this issue with Thunderbird 78 or later?
