>>> My Info: Win7_64, Nightly 49, 32bit, ID 20160526082509 STR_1: 1. Open url [1] 2. Hover mouse over checkerboard area, start rotating mouse wheel down 3. Move mouse to the right from the vertical scrollbar of iframe (while you keep scrolling) 4. Continue scrolling AR: The page doesn't scroll ER: The page should scroll STR_2: (reference of good behavior) 1. Open url [1] 2. Hover mouse over checkerboard area, start rotating mouse wheel down 3. Move mouse to the leftmost pixel of the page (while you keep scrolling) AR: The page immediately scrolls down, just as expected STR_3: (reference of good behavior) 1. Open url [2] 2. Hover mouse over checkerboard area, start rotating mouse wheel down 3. Move mouse to the right from the vertical scrollbar of iframe (while you keep scrolling) AR: The page immediately scrolls down, just as expected Note: Yes, I'm aware that mouse scrolling stays connected to one scrollable area (s.a.) while I keep rotating mouse wheel and keep mouse pointer inside SA_1 (even if I hover mouse over some inner scroll area (SA_2)). But I'm also aware that if I move mouse outside of SA_1, scrolling looses connection to SA_1. Usually. But not in this case. So, this bug report assumes that in Step 3 reporter moves mouse outside of original s.a., and therefore scrolling should stop.

I can sort of reproduce this. using STR_1 and STR_2. I think what might be happening is that when the mouse moves left it hits a different target than the content, or something. Not really sure but it warrants investigation.
