ID 235715 - Patch bleed state via Python is seemingly ignored

Problem summary
When disabling Patch bleed via Python, on export this preference is ignored and all patches are still bled over the UV islands.
Customer reported version

3.0v4

Customer reported platform
Linux

Steps to reproduce

1) Launch Mari, Open up the default Head project.

2) Open the Python Console and run the following code: 

channel = mari.geo.current().currentChannel()channel.setBleed(False)for layer in channel.layerList():    layer.setBleed(False)

3) Then go to Channel > Export flattened > Export 

4) Observe that the patches have bled over the UV islands. 

Workaround
Exporting as individual layers, with a UV mask enabled seems to work.
