Using `ctrlSetStructuredText` on with structured text *edits* this structured text object.
For example on a RscStructuredText control:
```
private _text = "abcd";
private _parsedText = parseText _text;
_myControl ctrlSetStructuredText _parsedText; // will change _parsedText value
For example, `_myControl ctrlSetStructuredText _parsedText` will change _parsedText value. _text // circumvents the issue
`_myControl ctrlSetStructuredText parseText _text` circumvents the issue.```
Thanks to @Dscha for finding it out.
