Two problems :
 

• The maxHeight of the dialog (for instance add-user-link-dialog) are set and not configurable. So when we want to modify the form, we have to override the `add-user-link-btn-script` template to override the max-height too.

• When overriding the form of these dialogs (ie `add-user-link-dialog-and-form`), it is impossible to use the `add-link-bl` template (as the dialogs are set inside <script> tags), and using the `bookmarklet-javascript` template is also impossible as both ' and " characters are used to delimitate the strings inside this template.
