The Files/History HorizontalPager and the diff view's own horizontal code
scroll were both trying to consume the same drag, causing jittery scrolling
and text intermittently scrolling out of view. Disable the pager's own
swipe gesture whenever the current tab is showing scrollable source text,
re-enable it everywhere else. Root cause diagnosed live by the human
product owner from watching the behavior directly.
