Bug 277666 – Inputs with overflowing content cannot be scrolled within an iFrame.

• Status: RESOLVED
• Resolution: FIXED
• Component: Scrolling

[Simeon Cheeseman]

This may be a regression of https://bugs.webkit.org/show_bug.cgi?id=188374 and we've confirmed it occurs in iOS 16 and iOS 17.

To replicate;
1. Open https://codepen.io/team/tablecheck/pen/LYKLRmj/84e3741f7a8cafa7547bb8b215b76c63
2. Inside the iframe, type or copy in "START - test test test test test test test test test - END"
3. Try to scroll the input field back to see the "START" string

Neither long press and drag nor long press the on-screen keyboard and moving the cursor cause the input content to scroll and the "START" cannot be found.

For future reference — this never worked in WebKit2. #188374 is only about handling updates to the selection endpoints during text interactions on iOS, whereas this bug is about autoscrolling.
