Table headers not visible on mobile

Hi ,

Table column headers are not visible on mobile phone.
Tried on iphone 6s & X - ios 12 ( both safari and chrome).

I initially thought its some sort of configuration or cache issue, but it happens on grafana demo site as well.

Am I missing something or no one is using grafana on phone ?
