Recipient search text is not selected after choosing a contact in multi-recipient picker

Bug description

In multi-recipient flows such as forwarding messages, after selecting a recipient from the search results, the current search text remains in the recipient search field but is not selected.

Because of that, searching for the next recipient requires an extra manual step each time: clearing the field, backspacing the old query, or manually selecting the text before typing again.

This makes repeated recipient selection slower than expected in flows that stay open after each selection.

Steps to reproduce

1. Open a multi-recipient flow such as message forwarding.
2. Type part of a recipient name in the search field, for example Ali.
3. Select that recipient.
4. Immediately try to type the next recipient’s name.

Actual result

The previous query remains in the field and is not selected, so the next input appends to it or requires manual clearing/replacement.

Expected result

After a recipient is selected, the existing search text should remain visible but be fully selected, so the next keystroke replaces it immediately.

Additional context

This appears most relevant in multi-recipient flows that stay open after each selection. Single-select flows that immediately navigate away are not materially affected.

Start by reproducing the multi-recipient forwarding flow and tracing the recipient search field after a contact is selected. Done means the existing query remains visible and is fully selected so the next keystroke replaces it; verify that single-select flows are not materially affected.
