Environment

Windows build number: 10.0.18362.0
Windows Terminal version (if applicable): master

Any other software?

Steps to reproduce

  1. Minimize the height of Terminal. Doesn't even have to be fully minimized.
  2. Create a new tab

WindowsTerminal_cY56ao4860

Expected behavior

A new tab is created

Actual behavior

Terminal crashes

Details
Terminal crashes with the exception Unhandled exception at 0x00007FF8AB012830 (Windows.UI.Xaml.dll) in WindowsTerminal.exe: 0xC000027B: An application-internal exception has occurred (parameters: 0x0000027E170823C0, 0x0000000000000002).

This should be the actual error.

E:\Code\terminal\src\renderer\dx\DxRenderer.cpp(247)\TerminalControl.dll!00007FF835C818E6: (caller: 00007FF835C7CBCB) ReturnHr(1) tid(2944) 887A0001 The application made a call that is invalid. Either the parameters of the call or the state of some object was incorrect.

    [Microsoft::Console::Render::DxEngine::_CreateDeviceResources(_dxgiFactory2->CreateSwapChainForComposition(_d3dDevice.Get(), &SwapChainDesc, nullptr, &_dxgiSwapChain))]

// src\renderer\dx\DxRenderer.cpp(L233-249)
case SwapChainMode::ForComposition:
{
	SwapChainDesc.Width = _displaySizePixels.cx;
	SwapChainDesc.Height = _displaySizePixels.cy;
	
	// omitted

-->	RETURN_IF_FAILED(_dxgiFactory2->CreateSwapChainForComposition(_d3dDevice.Get(),
																  &SwapChainDesc,
																  nullptr,
																  &_dxgiSwapChain));
	break;
}

Height is 0 which I assume is an invalid parameter.
