Display: flex has no effect on some (all?) Ionic-elements

Hi there,

setting display:flex for e.g. ion-toolbar or ion-item in V5 doesn’t has an effect. Chrome says the property has been set properly but that seems not the be the case. I think I know how to deal with styling web components and tried different approaches (including ::ng-deep) but with no success. I also can’t override any CSS-variables dealing with “display” as Ionic doesn’t offer one. And btw. I know that there are “slots” but sometimes their not enough for styling some layouts.

Has anybody found a solution for this and/or can explain why this happens?
