MVT Clone Fix
Description
Bug fix here.
If entry.Layer is undefined - ie the layer to clone is not accessible, and the entry has no zIndex. The code attempts to set the
entry.zIndex
toentry.Layer.zIndex
. But asentry.Layer
does not exist, it crashes.To fix this I simply swapped the code around. This way - if the entry.Layer does not exist then the return happens and no crash occurs.
