A field in my PDF has the Scroll long text option set. When I fill in this field programmatically, it does not render properly: the plus sign displays, but not the text (initial display.PNG). If I hover over the field, the field border shows (hover.png). If I then click the field or the plus sign, the text displays (and the plus sign vanishes) (clicked into.PNG). If I then click off the field, the display reverts back to the initial display of just the plus sign (initial.PNG)
However, if I click into the field and type some additional text, then click off the field, the text and plus sign display (after typing.PNG). It would be nice, I think, if this last state was what happened initially.
If I don't have the Scroll long text option set on the field, the initial display shows the field without the plus sign, but the text is offset to the south (NOT Scroll long text.PNG) which also seems wrong; I could live with this not having the plus sign indicator if the text wasn't offset.
