Scrolling in the editor window now hides the source code

[dargilco]

Type: Bug

A regression happens in the latest code-insiders. I search for something in my Python project. I open the relevant file that had the pattern I was searching for. Then I scroll in the editor to see the Python file (either with window slider or mouse roller). Instead of the source code scrolling up and down, I now see lines of source code being hidden as I scroll up and down. Seems like there is a bug in showing source code while scrollingl

Can you try the newest insiders and share a gif if possible

@benibenj I did not see in the last couple of days, so I'm assuming this bug was fixed. Thank you, I'm closing this issue.
