A custom lightning component has been developed with `<lightning:helpText>`. It is performing as expected in Web Browsers and Android deviced.

The Helptext doesn't hide even it is clicked anywhere on the screen or navigated to other page.



Affected in all iPhones. Screenshots taken with v12.0.1 using Salesforce 1 app.
