Topic: Console: Added non-passive event listener
Expected behavior
clean console ;)
Actual behavior
console output: mdb.umd.min.js?15b7:7 [Violation] Added non-passive event listener to a scroll-blocking 'touchstart' event. Consider marking event handler as 'passive' to make the page more responsive. See https://www.chromestatus.com/feature/5745543795965952

Code
<MDBSideNav

id="sidenavMDB"
contentSelector="#page-content"
:modeBreakpoint="1400"
:closeOnEsc="true"
>
tags || nothing
</MDBSideNav>
Hi,
We have checked this issue and there is not much we can do about it. To get rid of these warnings, turn off verbose mode in your console. We can't make these events passive because we use preventDefault in all of them and use our custom behavior. Making them passive will break our components. After all, these are just warnings, not errors and there should be no performance issue or code failure.
Keep coding,
Dawid
