PDF Viewer does not support page=Fit (only FitV or FitH works)

[BenjyTec]

I found that the Edge PDF Viewer does not allow to display a PDF so that its first page fully fits into the window (no part of the PDF is out of the viewport) while using the URL parameter view=Fit.

You can use the following URL to verify:

Case 1

When the window width gets too small, the window will display a horizontal scrollbar instead of scaling the PDF to fit the width:

When I use FitH, this specific case works.

Case 2

When the window height gets too small, the window will display a vertical scrollbar instead of scaling the PDF to fit the height:

When I use FitV, this specific case works.

Expectation

PDF_Resize.mp4

With Fit, both cases should be respected, but in fact no case is working. When I test the same parameters in other Browsers that use a Chromium engine, it works.

Setup:

Microsoft Edge Version 141.0.3537.85 (Official Build) (64-Bit)
