- since resetForm function reset a field value a calculateNow is consequently triggered. But the calculate callback can itself call resetForm, hence an infinite recursive loop. So basically, prevent calculeNow to be triggered by itself. - in Firefox, the letters entered in some fields were duplicated: "AaBb" instead of "AB". It was mainly because beforeInput was triggering a Keystroke which was itself triggering an input value update and then the input event was triggered. So in order to avoid that, beforeInput calls preventDefault and then it's up to the JS to handle the event. - fields have a property valueAsString which returns the value as a string. In the implementation it was wrongly used to store the formatted value of a field (2€ when the user entered 2). So this patch implements correctly valueAsString. - non-rendered fields can be updated in using JS but when they're, they must take some properties in the annotationStorage. It was implemented for field values, but it wasn't for display, colors, ... - it fixes #14862 and #14705.
