Bug 253326

Summary: User-defined variables should not scroll out of view when stepping over/into code
Product: debugger Reporter: _ gtzabari <gtzabari>
Component: CodeAssignee: Martin Entlicher <mentlicher>

Severity: normal

Description _ gtzabari 2015-07-06 20:22:44 UTC 
Repro steps:

1. Start a debugging session, hit a breakpoint.
2. Add entries to the Variables tab until you are forced to scroll downward to see the last entry.
3. Hit F7 or F8 to step into or over a line.
4. Notice that the Variables tab jumps to the top scrolling position

This is a major usability problem, because it means users cannot add more than 4-5 variables without having to keep on scrolling them into view each time they use the debugger.

Expected behavior: Scrollbar should maintain position across stepping operations. If the scrolling position no longer exists, jump to the lowest scroll position.
