on every form control page, there are the sentences:
"Form controls are actual HTML elements floating above the game canvas in the HTML page. Therefore, nothing can be displayed on top of a form control, apart from other form controls.
Form controls position themselves according to the layer parallax, scale and so on. However they are not truly "in the game" (since they float above), so it is recommended to avoid using scrolling, parallax and layer scaling with form controls, otherwise the end result can feel unnatural."
however it does not appear in the filechooser page https://www.scirra.com/manual/182/file-chooser
