If you search for "hello", then the word "hello" will once again
be highlighted yellow in the messages.

One of the ugly parts of message_list.js is how it re-uses the message objects
from the server to hold handlebars template parameters. These objects are
shared between different message lists and re-renders, but are mutated by the
rendering process. The `dom_id` attribute is normally unset on summary rows,
and should not be used in the template. But when a message comes in with a
`dom_id` from another render, it can end up on the summary row, breaking
`rows.get()`.

When you read messages in a narrow and then un-narrow, collapse
adjacent messages read in the narrow into a summary row that can
be clicked to expand those messages.
Scoped to staging with feature flags.
The implementation of this within our current MessageList is rather ugly.
