Patch Changes

• #4603 ca030a6 Thanks @martinfrancois! - Stop adding PostHog's optional feature scripts, such as the session replay recorder and exception autocapture, to the page more than once. Sites that proxy PostHog through their own domain, by setting api_host to a path like /ingest rather than a full URL, ended up with the same <script> tag three or four times: the check meant to spot the duplicate compared the browser's resolved absolute URL against the relative one, so it never matched. The network tab showed a single request either way, because the browser served the repeats from its cache, which is why this was easy to miss. Nothing measurable got slower as a result, so this is a correctness fix rather than a speed one.

• #4453 325870a Thanks @posthog! - When session replay is waiting on a trigger, debug mode now names the conditions that haven't matched yet (for example buffering: URL condition not matched, or the named trigger group whose condition is pending) instead of only reporting buffering. Enable it with posthog.debug(). Logged once per change, not once per flush.
