formio: Form iframe (resizer) height issue

[bobslee]

As shown in screenshot, there's an issue with the form canvas its height - auto scaling.

Have to find out whether its a CSS issue or due to a misconfiguration in the included iFrame Resizer library:

Suggestions:

• Maybe upgrade the iframe-resizer library
• Replace iframe-resizer by a different library eg. seamless https://github.com/travist/seamless.js ?
• Any other idea?

Experiment:
When changing the Javascript in file: formio/static/src/xml/formio.xml, to:

iFrameResize({heightCalculationMethod: 'lowestElement'}, '#formio_form_embed');

=> Initially (first click) works.
However not after closing the Select component - then the iframe just doesn't resize (downsize)!

The option heightCalculationMethod doesn't make any difference with values: max, grow or lowestElement.

Maybe I've a workaround for this issue. Still experimenting tough.
