      Handle port requests from guests with opaque origins · 905077aa
      Robert Knight authored 
      When a guest frame with an opaque origin, such as file:// URL or a sandboxed
iframe, sends a request for a port to the host frame, the `event.origin` value
will be the string "null". This is not a legal value for the `targetOrigin`
argument to `postMessage`, so we need to remap it to "*" (any origin).

      Remove a test which doesn't test what it intends to · a9ce9227
      Robert Knight authored 
      Dates are in fact JSON-serializable, but as strings.

Recent changes to `isMessageEqual` mean that the `JSON.stringify` calls
cannot fail, because the `isMessage` check ensures all the fields we
serialize are strings. Writing a test to check for this failure mode is
not possible. There is a refactoring hazard here, so I added a comment
to call this out.

      Ignore unknown keys when checking payload / message match · 28fa4e8c
      Robert Knight authored 
      When comparing a MessageEvent's data to an expected message, only
compare the known fields of the message and ignore any unknown fields.

Unknown fields don't cause problems for us in parsing the message, and
there is a risk that it might cause us to silently ignore messages in
some environments. We don't know yet if that actually happens.

      Rebuild boot script when modules in src/boot change · 97a71736
      Robert Knight authored 
      Previously the boot script was not regenerated when its JS inputs
changed, as opposed to the JSON manifest.

This approach relies on `src/boot` not having dependencies on other
modules. We could improve this by using `watchJS`, but that currently
produces too much distracting log noise when running `make dev`.

      Serve boot script with correct mime type · 251410ca
      Robert Knight authored 
      It was previously served as text/html, which caused warnings in some
contexts.

      Modernize browser check logic · 7173bde9
      Robert Knight authored 
      Update the representative feature tests to check for Shadow DOM v1 and CSS grid.

This avoids loading the client in browsers that are definitely too old.

      Fully un-set user-focus filter when empty user is passed · 791c4bf2
      Lyza Danger Gardner authored 
      Fix a UI confusion by fully un-setting the user-focus filter if a
empty user value is provided to the `changeFocusModeUser` RPC method.

This prevents a confusing half-set user-focus filter from sticking
around when an instructor returns to viewing all users in grading mode
after focusing on one or more students.
