If you put curly braces (e.g. "{}") in macro string parameters, the macro is likely to break in the WYSIWYG editor, but it will work on the final page. If you escape the curly braces like

\{

it will work in WYSIWYG, but show a wrong result on the real page

What will break?

• If it's a macro with macro body, the preview will lose it's icon and it's description text (name and selected parameters).
• If it's a macro without a body, the preview gets stuck loading with all controls like "save" or "preview" disabled.

How to reproduce

1. Edit a page with WYSIWYG Editor
2. Add a macro (panel macro for "macro with body" or gallery macro for "macro without body")
3. Edit the added macro in Macro Browser
4. Enter some text with curly braces into a string property field
   • e.g. use the text test{ - opening curly brackets are more likely to break everything
   • for the panel macro you can add the text to the param "title"
   • for the gallery macro you can add the text to the param "title", too
5. Hit the Macro Browser's save button.
6. Look at the macro in the WYSIWYG Editor
   • the panel macro won't have an icon or text anymore, the bar at the top will be blank
   • the gallery macro got stuck loading, blocking the "save" and "cancel" controls
