There were two typeahead displayed while we were testing
create_private_message_draft. One was topic typeahead from previous
create_stream_message_draft test and the other was cordelia
DM typeahead. So, when clicking on the typeahead, we clicked
the topic typeahead when we really wanted to select the cordelia
typeahead. This resulted in drafts test failing.
This also introduces a combo grid/flex layout, which will also be
applied to the DM and Streams headings.
Because there are now multiple classes referenced from the
Puppeteer tests, those selectors now include the expanded
navigation area's parent ID selector.
In commit 5edc8fc, abstract classes were added to the
drafts overlay, but the classes that were already there
were not removed. This resulted in the same styles being
applied twice.
Previously this dropdown was only for selecting streams, but
soon it will also be for switching to a private message. This
name helps it be clearer that the dropdown is more general
purpose.
Fixes#11832
This lets the user see more options than the three that appear
in the typeahead menu, and prevents them from inputting invalid
stream names.
This change replaces the input field with the dropdown, and
updates everything that referred to the classnames of the old
input field, so that they now get the data they need from the
new dropdown.
