Custom Visual Developer console not logging

In Firefox (Chrome does not work due to stricter unsigned TLS rules in OS X, despite setting keychain...), the developer console does not show calls to console.log/console.info, any ideas?

 

We're trying:

- update() calls console.info() + alert() as their first thing

- the test: use the Format panel UI to manually change some values, expect to see update()/enumerate called for our custom objects

- logExceptions decorator (calls console.error for update() exns): https://community.powerbi.com/t5/Developer/How-to-Debug-while-developing-Custom-Visuals/m-p/187053#M...

 

Overall setup: https://community.powerbi.com/t5/Developer/Custom-Visuals-format-panel-input-values-reset-1-second-a...

Sorry, I have little experience in this custom visual. @dm-p  is very outstanding. Could you please help to solve this problem?

The plot thickens:

 

 

--  `Visual::constructor()` and `Visual::enumerateObjectInstances()` will print via console.info()

-- ... but `Visual::update()` will not print console.info() after changing a custom value in the Format panel

 

Also, we rolled back the API version  to 3.8.3 to match the bar chart demo repo

 

So, the question comes: Why is update() not getting called / not calling console when Format pane custom text input values get manually changed by the Report editor user?
