Using setMolecule with molfile does not rescale bond lengths

1. Using ketcher standalone, import the molfile above using ketcher.setMolecule
2. Import it again but using the Open... > Paste from clipboard option

Actual behavior
The two benzene rings are different sizes.

Expected behavior
I would expect setMolecule to scale the bond length in the same way as the Open... menu.

Screenshots
In the image below, first benzene was added with setMolecule, second benzene was added via Open... menu button, third benzene was drawn with benzene button.

Ketcher version [e.g. v2.4.2].
Tested in v2.6 and v2.11

Hi, could you confirm whether this is a bug or if there's a workaround? We just want to be able to set a molfile programmatically and have the drawing be re-scaled. Thanks!

Hi @mliu49,
Thank you for raising this issue.
We reproduced it and planned to v2.19.

Tested. Fixed.
