Modernizr CSS VMIN

[longridge]

Within a couple of websites I've written, I test for css feature VMIN - using modernizr 3.5.0.

With android chrome and ipad (safari) - Modernizr identifies VMIN as fine - i.e. a positive test when in portrait mode - but the same test applied to same browser in landscape mode fails. (Chrome on IPAD is recognised whether portrait or landscape). IS this an issue for the modernizr test ie what is modernizr checking to identify the support for VMIN?
Issue can be seen by reference to music website http://www.northfyldemusiccircle.org.uk and "inspecting" the css tests supported by modernizr.

what is modernizr checking to identify the support for VMIN?

feature-detects/css/vminunit.js

[longridge]

The full test I use (built around an "if else" statement) is :

Modernizr.mq("only all") && Modernizr.cssvwunit && Modernizr.cssremunit && Modernizr.flexbox && Modernizr.boxsizing && Modernizr.cssvminunit && Modernizr.mediaqueries

The key feature which seems to cause a problem (in circumstances covered earlier) is
"Modernizr.cssvminunit"

Code can be seen using web inspector tools on site referred to in opening note.
