Environment

Windows build number: 10.0.18363.0
Windows Terminal version (if applicable): 0.7.3291.0

Two displays on same nvidia GPU (441.41 drivers). Primary is 2560x1440, secondary positioned to the left is 1920x1200.

Steps to reproduce

Use powershell $Host.UI.RawUI.WindowSize to check dimensions of terminal both maximized and fullscreen.

Expected behavior

Fullscreen terminal should report at most a handful of extra rows/cols compared to a maximized window (accounting for space consumed by window border/task bar).

Actual behavior

For primary monitor as expected:
Maximized: 229x61
Fullscreen: 231x63

On secondary monitor gigantic width in fullscreen:
Maximized: 171x50
Fullscreen: 348x52

The fullscreen window itself is still correctly sized to the display. The left/top/bottom edges of the terminal content are aligned to the matching edges of the window (or approximately when fullscreened directly from maximized ala #3709). The extra columns aren't visible beyond the right edge of the window.
