Summary0018228: Undo after delete line does not move caret to correct position
DescriptionAfter a line is deleted and Undo is issued the caret moves to the top of the edit window but does not change to the Y position where the line was deleted.

To reproduce:
Open a file in IDE, move the caret to some line and delete the whole line (Ctrl+Y; or Shift+Down to select and Delete to remove). Press PgUp or PgDown a few times to move the deleted line out of view. Press Ctrl+Z to undo, the cursor will move to top of the edit window but the window will not be scrolled back.
TagsNo tags attached.

to verify I understand correct:
- Say the caret is on line 130 x-pos 1, this line is centered to the window
- you delete this line.
- you scroll away from the line
- you press undo
- line 130 is restored, and the caret is in line 130 pos 1
=> but line 130 is now on the top (or bottom) of the window, instead of being centered.

Is the above description correct, or do you mean the cursor will be position in a different line (e.g line 120) ?

If the above is correct, this is the indented behaviour.
Scrolling is not an undo-able action.

The caret will return to the correct text-line (130).
If this line is out of view it will be scrolled into view, but not centered.

partly fixed in 28726.

The caret now moves back to the correct position, and this position becomes visible.

However, if you mark an entire line with Shift cursor down, then the caret was just under the deleted line.
that means if you deleted line 120, and the caret was on 131 then it goes back to 131. And topline will also be 131.
So the restored line itself is not shown ...

Still working on...
