1220781 - "Advanced" button on certificate errors doesn't work on cert errors in frames or badStsCert - @hidden vs. style.visibility = "hidden"

Status: VERIFIED FIXED

Description

[Matthew N. [:MattN] (PM me if requests are blocking you)]

I received sec_error_unknown_issuer on a site in a frame and the "Advanced" button wasn't functional.

The advanced section had @hidden=true but the button was only toggling `style.visibility` on the contents.

I suspect this is a regression from bug 1207107 as it touched related code (visibility/hidden).

According to a comment in aboutCertError this is attempting to disallow an override: https://dxr.mozilla.org/mozilla-central/source/browser/base/content/aboutcerterror/aboutCertError.xhtml#94-96.

Instead of hiding the advancedPanel I think we should be hiding the exceptions button.  This will more closely match the behavior before the UI change.

I don't have test pages handy to test this but it seems plausible that this fixes my issue.

Thanks for the review.  This case is also triggered on any cert error page in a frame, so this should reproduce it also: data:text/html,<iframe src='https://expired.badssl.com'></iframe>

Approval Request Comment
[Feature/regressing bug #]: 1207107
[User impact if declined]: User won't be able to view advanced details for non-overridable cert errors
[Describe test coverage new/current, TreeHerder]: New test case
[Risks and why]: Changing the selector of an element that's getting hidden in JS on the cert error page and that element will always exist (from the HTML), so it's not a very big risk.
[String/UUID change made/needed]:
