1795818 - Dragging splitter between AddressBar and SearchBar does not follow mouse movement

Status: RESOLVED WONTFIX

(Core :: XUL, defect)

Description

[Alice0775 White]

Steps to Reproduce:

1. Enable standalone Search Bar.
2. Drag the splitter to resize the search bar.

Actual Results:
When dragging the splitter, the amount of the drag is less than the movement of the mouse.
And spring elements on both sides of the address bar and search bar change width.

Expected results:
The amount of drag should be same as mouse movement.
The spring erements should not change the width.

:emilio, since you are the author of the regressor, bug 1794630, could you take a look? Also, could you set the severity field?

Ah, that's pretty minor, and unfortunately kind of expected (to avoid the jumping you were seeing, and also to make the searchbar on new windows have the right size).

We can't quite just follow the mouse precisely, because the searchbar is flexible and adapts to the available space (it shrinks / grows when the window size changes). The previous behavior made the searchbar have different size when in a new window, which was a bit weird as well.

I think this is WONTFIX unless you are also seeing weird jumps or so.
