InternetMessageId is blank in SelectedItemDetails when selecting an email while searching

[MohamedMoussaTTW]

When selecting an email after doing an email search, the internetMessageId when calling getSelectedItemsAsync is blank.

Seems to occur only in Outlook Classic.

Environment

• PC Desktop
• Outlook (Classic)
• Office version number: Office 365 MSO Version 2411 Build 16.0.18227.20082
• Windows 10

Expected behavior

When clicking on an email, I expect the internet message Id field to be filled.

Current behavior

The internet message Id field is not filled in getSelectedItemsAsync callback when clicking on emails during a search.

Steps to reproduce

1. Select an email and call getSelectedItemsAsync. The internetMessageId field will be filled in the callback.
2. Do a search and select the same email again. The internetMessageId field will be blank

Possible solution (Extracted from existing issue, might be incorrect; please verify carefully)

The issue here seems related to the format of the internetMessageId which is enclosed in <>. The value is being assumed as a HTML tag and hence, not being displayed in taskpane. You just need to change "innerHTML" to "innerText" and keep the remaining code as it is. Could you please try that?
