Vscode: Output Channel does not scroll down automatically

[formulahendry]

• VSCode Version: 1.26
• OS Version: Windows 10

Reported from Code Runner users: https://github.com/formulahendry/vscode-code-runner/issues/342

In previous version of VS code, it works normally.

Works fine for me in latest vscode insiders
Can you reproduce with insiders https://code.visualstudio.com/insiders/

If yes please create a minimal reproducable sample extension.

Same issue here, the output window does not automatically scroll down

[formulahendry]

Install the Code Runner could easily repro.

In Command Palette, type Run Code to run any file.
If run put focus on Output Channel, the scroll down will stop, in previous version:

Then in Command Palette, type Stop Code Run, then Run Code again, the scroll down also not work.

This is because of the Smart scrolling behaviour - https://github.com/Microsoft/vscode/issues/49110

Last line is not revealed if you focus on some text.

@isidorn FYI

I would argue that in some case, it would be a bug, or say it is not smart enough. User never have focus on the Output Channel, but the Output Channel is not scrolled. Previous always scroll would be better. Or there would be better to have a setting to config the behavior.
