Editor freezes when adding certain content to Toolset Address Field Marker pop-up

Symptoms

Toolset allows you to display a map populated by markers whose addresses come from a View.

Adding certain kinds of content to the editor for the marker pop-up can cause the edit page to freeze, requiring you to close and re-start the browser window.

These are known to include non-Toolset shortcodes, inserting a Types video field, and also conditional shortcodes.
