Retaining zoom on mobile browsers after updating from .NET 2.0 to 4.0

Question

We have a website written in ASP.Net and is often used on mobile phones or tablets. Before upgrading from .Net 2.0 to .Net 4.0, mobile users were able to zoom in, click a button, and the page would refresh to the exact same position and zoom level. Now when they click on a button while zoomed in, the page becomes zoomed out on the refresh.
It appears as if the maintainscrollpositionOnPostBack is not working on phone's browsers.

Is there a way too keep the zoom level and position on the refresh?

What I have tried:

There does not appear to be a setting outside of maintainscrollpositionOnPostBack. We were looking into attempting to save the position and zoom and then putting it back on the refresh.

As far as I know, browsers control the zoom and not ASP.NET (regardless of version 2, 4 or the vNext).

Was ASP.NET handling the zoom manually?

No, the maintainscrollpositionOnPostBack seemed to do the trick on 2.0.
