OWA Outlook won't launch add-in (pane) when viewing a search result.

Your Environment

• Platform [PC desktop, Mac, iOS, Office on the web]: OWA
• Host [Excel, Word, PowerPoint, etc.]: Outlook
• Browser (if using Office on the web): Chrome

Expected behavior

At all times when reading a message (in a folder, mailbox, search results, etc), a ReadPane add-in can be launched.

Current behavior

When viewing search results and clicking on an item, you cannot (reliably -- sometimes it worked, others it did not) open a ReadPane add-in.

Steps to reproduce

1. Open your mailbox
2. Perform a search that results in some emails being shown
3. Click on one
4. Attempt to open an add-in (i.e. Hubspot) (tried from "All Apps" modal, pinned icon, etc)
5. Notice no add-in is opened. No error logs in console and no network calls

Useful logs

• You can see it works initially, but the next attempt no add-in can open.

Thanks for the clear repro steps and the Loom video — this is extremely helpful.

We’re routing this to the Outlook Web engineering team for investigation.
