Can't change description text for Azure Logic App trigger from within VS Code designer

### Severity

P3 - Medium (Minor functionality affected)

### Describe the Bug with repro steps

I have a few Azure logic apps that I am trying to edit within VS code. Using the designer UI for each flow, I click on the trigger within that flow to bring up the properties tab for the trigger. In my case, these triggers are Azure Event Grid triggers. I then try to add a description and save the changes by clicking the Save button.

When I do this, it seems that the first character of what I type into the description field gets saved, but all other characters are truncated. For example, if the description is initially empty and I add the text "This is a text description", press save then the description of "T" will be saved. This was verified by looking in the workflow JSON file's "description" property for the trigger. I then go back into the trigger description and change the "T" to "This is a text description". When I press Save again the description is now set to "Th". And so on.
