Behaviours not working after Chrome 81.0.4044.92 Update

Steps to repro:

Upgrade Chrome to 81.0.4044.92  or above 

Create single select custom field

Attach behavior script to another field that updates options of that single selects.

i.e. 

def f = getFieldByName('test')
f.setFieldOptions(["-1": "None", "10003": "1", "10004": "2"] )

Workaround: 

Use a browser besides Chrome in the meantime
