As stated, In VS2017 my asp.net mvc application submits a null value when refreshing and "resubmitting" (for a built in search) in chrome only. All other browsers work normally. Google search has yielded nothing useful. I'm not sure where to begin.
This issue applies to Version 60.0.3112.101 (Official Build) (64-bit)
Google seems to know about this issue, they have a bug ticket opened at https://bugs.chromium.org/p/chromium/issues/detail?id=747812.
Doesn't help us right now, but good to know that it's not an issue with our code!
