Better handle large display and text scaling on EDU tooltip.

For large scaling configurations, the tooltip height can exceed the
available space, which can truncate important content such as the "Done"
button. To mitigate this issue, we should attempt to increase the width
of the tooltip to hopefully free up some height due to the text taking
up fewer lines.

To support dynamic width, each EDU column gets an equal weight in the
ConstraintLayout, but the lottie animations are still constrained to
their original dimensions. If they fill the width, their aspect ratio
will be maintained and we will still have height issues.
