97973 - drag scrolling jumps on certain pages

Status: RESOLVED DUPLICATE of bug 59366

(Core :: DOM: Selection, defect)

From Bugzilla Helper:

Certain pages that mix text with images cause the behavior of drag scrolling to
"jump" down the page rather than smoothly scroll when scrolling between the text
and images.

Reproducible: Always
Steps to Reproduce:
1. Go to http://us.imdb.com/CommentsShow?130827
2. Scroll to the first comment.
3. Click right before the image that says "Email this comment to a friend"
4. Drag selection along text to the image.
5. Watch scrolling jump down the page.

or

1. Go to

2. Scroll to the first user comment.
3. Start selecting text right _above_ (not beside) the first image that says
"yes/no".
4. Continue selection down onto image.
5. Watch selection "jump" down the page.

Actual Results:  Browser "jumps" down the page. Selection maintains integrity.
That is, even though the act of selecting causes page to scroll incorrectly, the
selection always highlights text between start of selection and current position
of mouse cursor.

Expected Results:  Browser does not start scrolling while selecting unless a
selection moves beyond the top or bottom of page. And when this happens,
scrolling moves smoothly instead of "jumping".

This has affected every mozilla I have ever used, but I finally got annoyed
enough to report it as a bug.

Workarounds: This bug does not block any functionality. You can almost always
select the text you want if you are careful, or if you select it piecewise
around the troublesome images.

Marking these all WORKSFORME sorry about lack of response but were very
overloaded here. Only reopen the bug if you can reproduce with the following steps:

1) Download the latest nightly (or 0.9.6 which should be out RSN)
2) Create a new profile
3) test the bug again

If it still occurs go ahead and reopen the bug. Again sorry about no response
were quite overloaded here and understaffed.
