[BUG] change event giving isModified:false on any changes in signature component. #1155
Description
- Formio.js version: "~4.14.13"
- "@formio/angular": "~5.5.0-rc.10",
- Browser: ALL
Steps to Reproduce
In the signature component, when drawing on the signature pad or refreshing it, the (change) event emitter from
<formio (change)="onDataChange($event)">
is consistently emitting "isModified: false".
However, since the data is being modified, the expected behavior is for it to emit "isModified: true"

Is this the case with more recent versions?
