1120094 - Dragging scrollbar-dragger when text is selected doesn't work

Status: NEW

(Core :: DOM: Selection, defect, P5)

Description

Attachment: scroll.png

Select text like in the screenshot. It's easiest when click-dragging from the posting to the Google-logo

Try to drag the scrollbar-dragger does not work, it only moves a few pixels and then you have a translucent "preview" of the selection next to the cursor.

Scrolling with the mouse's scrollwheel or by clicking in the empty scrollbar-space above and below the dragger does work.

Reproduced in Win and Ubuntu.

Bulk-downgrade of unassigned, >=3 years untouched DOM/Storage bug's priority.

I hit this after accidentally selected content of the code block in https://bugzilla.mozilla.org/show_bug.cgi?id=1692276#c1 and then trying to scroll it (also reproducible after selecting whole page by Ctrl+A).
