Outlook Desktop, setSelectedDataAsync inserts HTML and ignores font size

[DmitryKostochko]

Provide required information needed to triage your issue

In an Outlook add-in for compose mode, we use the item.body.setSelectedDataAsync() method to insert HTML in the body of an item. The setSelectedDataAsync() inserts 11pt text instead of 12pt.

Your Environment

• Platform: PC desktop
• Host: Outlook
• Office version number: Version 2401 (Build 17231.20236)
• Operating System: Version22H2 (Build 19045.4046)
• Browser (if using Office on the web):

Expected behavior

The setSelectedDataAsync method shall insert HTML with the specified text size.

Current behavior

The setSelectedDataAsync method ignores the style attribute and inserts text with a font size of 11pt.

Steps to reproduce

1. Open the add-in's pane and execute the following code: Office.context.mailbox.item.setSelectedDataAsync("<p class=\"MsoNormal\"><span style=\"font-size: 12pt; font-family: 'Times New Roman', Times, serif;\">Must be Times New Roman, 12pt.</span></p>", { coercionType : "html"})`

2. As you can see, the font family was applied, but the font size was ignored.

Provide additional details

1. The issue is reproducible only in the classic Outlook desktop.
