This generates a notice, which wasn't seen because the feature works
asynchronously.

Previously, if the RSS feed (extests) was being served locally,
CFG->proxybypass was applied and causing the test to fail (proxy
ignored).

In that exact test we need the configured proxy to be applied
always, because the test is exaclty about detecting the problem
when a wrong proxy is used.

Some blocks (e.g. Calendar) load additional JS modules when returning
content. We need to make sure they aren't asked to generate content
unless the user can actually view the block, or the expected content
required by the JS will not exist in the DOM and can cause exceptions.
