[PDF24 Reader] How to scroll through multi-line text in an interactive ("fillable") form field?

It would appear that scrolling instead scrolls the entire page, and using the arrow keys, though they do move the inline cursor as desired, simultaneously scroll the page, making such largely unusable.

The only way I have found to scroll through such fields without scrolling the page is by highlighting text by dragging the cursor below the boundary of the field; however, the lack of precision while doing so leaves much to be desired.

I have the sneaking suspicion that there is currently no way to do so, but I wanted to check here regardless.
