Original Pull Request: https://github.com/microsoft/terminal/pull/10650

State: closed
Merged: Yes

Summary of the Pull Request

This fixes two bugs related to dragging into the bounds of the TermControl. Although the fixes are fairly small, I'm batching them up, because I don't want to stack 2 more PRs on top of #10051.

  • #9109
    • This is fixed by only starting an autoscroll if the click&drag actually started within the bounds of the control.
  • #4603
    • Building on the above change, only modify the selection when the drag started in the control.

Detailed Description of the Pull Request / Additional comments

This is kind of annoying that the auto-scrolling is handled by the TermControl, but it uses a timer that's still a WinUI construct.

We only want to start the auto-scrolling behavior when the drag started inside the control. Otherwise, in the tab drag scenario, dragging into the bounds of the TermControl will trick it into thinking it should start a scroll.
