Signature doesn't appear where field is defined

After signing, the signature appears below the signature field. It appears to be based on the original size of the field, regardless of how the field has been resized.

The expectation is that the signature should appear wherever the field has been placed on the document, so that it doesn't end up overlaid on other text on the document. If it's not going to appear where the field is posiitoned, it would be helpful to be able to preview the signed output, before sending a document for signing.

Also, ideally date fields should be able to wrap so they too don't end up overlaying other text in the document. Both illustrated in screenshot:
