- Stop looking up the topic title from the DOM. On long topics, the topic title may not be present. Instead, we can store the topic title in a data-title attribute during decorateCookedElement, and then access it later. This approach would also allow us to add customize titles per-local-date in future. If there is no topic title available (e.g. when local dates are used elsewhere in the UI), we use the site name to build a sensible default
- Don't require a postId for creating calendar events. We don't have postIds in non-post contexts. At the moment, the 'download ICS' function will fail without a valid postId, so that will need to be fixed in a future commit.
Previously we would render "Today at 2:42 PM"
Now we render "Today 2:42 PM"
This also introduces new strings so it can be properly translated
Finally it introduces tests so we can make sure this keeps working
