Other information

Stacktrace:

Error seems to be in frame.4.11.2 ?

Was able to get a little more information by catching all exceptions:

Apparently in FF, when getComputedStyle() is called inside an iframe with display: none, null is returned: link here

Thanks for the detailed report! The fix seems fairly straightforward.

Fixed in 4.11.3

@alavers

It looks like we're still running into the issue in v4.11.3:

Is there any other information I can provide you with? Thanks!

[alavers]

@kschiu yes looking closer now and it does seem the fix we shipped is helpful, but incomplete.

Can you share with me the context in which you're running v4.11.3? I wasn't actually able to reproduce this bug with Firefox 59.0.2, but if I had a reliable repro I'd stand a better chance at fixing it.

@alavers Could you explain what you mean by the context? Do you mean what our code is like? Or our environment?

[alavers]

@kschiu I'm asking about the page in which you're hosting the widget, since I'm unable to reproduce the issue myself.

In any case, I've implemented another fix that just went out with the 4.12.0 release. Could you re-test?

@alavers It looks good to me, the widget is now loading properly! Thank you for your help I really appreciate it!
