Issue Summary

When copying lists on a Board, some cards may be copied without all their labels applied. This results in some copied cards not being a true copy of the original card. This issue is intermittent; sometimes a copy works as expected, and sometimes it misses some labels.

Steps to Reproduce

1. Open a Board with multiple cards containing labels
2. Copy the list containing said cards to a new list on the board

Expected Results

I would expect the copied list to be a complete copy of the original list, including all the labels on each card.

Actual Results

Some cards are copied without all the labels applied.

Workaround

The issue is intermittent and occurs when there are a large number of cards in the list. Re-copying the list may result in a complete copy. If that fails, then you can reduce the number of cards in the list and attempt to recopy.
