Dragging vscode maximized from one window to another can hide terminal

[Tyriar]

I think the expected intersection observer events are not being fired.

Tested on Ubuntu 17.10

Workaround: Hide and show terminal or create a new terminal.

Also happening on Windows.

Here's a quick gif.

@Kurtz1993 I suspected this might also be happening, thanks for verifying 😃

This doesn't appear to happen in the xterm.js demo with Chrome v64, it might be related to either relayout in VS Code or a bug that's been fixed in Chrome that's still present in Electron.

I think it's the latter, that this is fixed in Chromium. I added a workaround to force the terminal renderer to resume when on layout of a visible terminal.
