@oliviaflory not sure if we can make adjustments for this before code freeze. Can this go into the next release?

This behavior will be implemented as documented in the functional specs. If the last option on the right is partially visible the menu will slide to the right for the small amount needed to expose the entire option. @photodow will find where the behavior is documented in the functional specs. If not documented, he will update the functional specs. This decision was made in a meeting with the India accessibility team members.
