Issue Status: ONGOING

Issue Description: Some users may see that adaptive card messages are incorrectly rendering on multiple lines in Microsoft Teams.

More info: If you’re using RichTextBlock in your adaptive cards with TextRuns that have their selectAction property set, unwanted line breaks show up. Your card, however, remains fully functional.

Current Update: 16/01/2025 09:15:00 AM – Microsoft have confirmed that the deployment of their fix is underway, and they are monitoring its progress with the aim of providing an estimated remediation timeline once it becomes available.

Scope of impact: This issue can potentially affect any user that’s viewing adaptive card messages in any Microsoft Teams connection method.

Root cause: The library used by Microsoft Teams to pull the adaptive card messages has an incorrect action definition, resulting in impact.
