bug: ion-tab-button not selected when using routeParams

[MartineFrancken]

Bug Report

Ionic version:

[x] 4.6.0 (ionic/angular)

Current behavior: When using a param in [tab] of an ion-tab-button, the ion-tab-button is not recognized as selected when navigating to the tab. Example: <ion-tab-button [tab]='patient/0'></ion-tab-button> When clicking this button, 'patient/0' route is called and the tab patient/0 is shown. But the ion-tab-button is not recognized as selected.

Expected behavior: I would expect that the ion-tab-button is recognized as selected.

Other information: I was able to find that an stackId is used internally to decide if an ion-tab-button is selected. stackId is looking to the url and only taking the part 'patient' and ignores '/0'.
