TextMeshPro multiline InputField scroll issues with PageUp/PageDown keys

Hi pals,

I'm having some issues when scrolling a multiline InputField using PageUp/PageDown keys:

Even if the text doesn't need to scroll, when pressing PageDown key, the text goes all the way down disappearing from view. Then, when trying to go up again using PageUp, it slowly scrolls up as you can see in the screenshot below:

I suppose this is a bug, but is there a workaround for this issue? As the source code of TMP isn't public and the legacy InputField...
