==== What is the problem?
The intake form will not load if the wish description includes parser tags (e.g. `<syntaxhighlight>`) that are not correctly closed.
For example, a description like:
```
<syntaxhighlight>
foobar sdjfkl sdjfkl sd jsklf sjklf sdjkfl sd
```
If you try to "edit with form" a blank intake form will load and the VisualEditor and Source Editor will not load for the description.
Also, in the browser console you will see this error:
```
