Content Scale lock works only in one direction

Summary:

When linking the scale of the viewbox to the scale of the content in the document, changes to the scale field affect the width/height fields of the viewbox section, and all objects and pages keep their size - it only changes 'the resolution' of the SVG without affecting how it looks.

When - in that state - then scrolling over the width / height field of the viewbox, this will still change the scale, BUT also the objects' sizes.

I had expected the link between both to be established in both directions, not only unidirectionally.

Steps to reproduce:

• open Inkscape
• draw a few objects of 100 x 100 mm, place them in page corners for ease of seeing the results
• open Edit > Document properties
• select to 'link the scale of the viewbox to the scale of the content'
• observe changes when changing viewbox and scale field contents

What happened?

• the lock keeps object sizes intact when scrolling over the scale field, but not when scrolling over the viewbox width / height fields.

What should have happened?

• not sure, but this seems strange to me. I'd have expected a link to go in both directions.
