Linear stepper stuck on the step after re-initialization

[ilinyhsergey]

What is the expected behavior?

After linear stepper reinitialization (f.e. web-app reload) all previously filled out forms of steps restore their valid state from storage and stepper restore selectedIndex. All these forms should be considered as visited and completed so user can navigate back without restriction.

What is the current behavior?

User completed step 1 and 2 and stay on step 3.
States of forms on step 1 and 2 are saved in storage.
After reload, forms on step 1 and 2 restore its states, so the steps are valid and selectedIndex set to step 3.
User can't navigate back to step 2, despite the fact that this step is valid. User can only navigate to step 1.

What are the steps to reproduce?

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

    "@angular/cdk": "^7.3.1",
    "@angular/core": "7.2.4",
    "@angular/material": "^7.3.1",
    "typescript": "3.2.4",

Windows 8.1; Google Chrome 72.0.3626.121;

Is there anything else we should know?

Can confirm, same issue

Happens the same.
Chrome 72.0.3626.121
MacOS Mojave 10.14.3

Blocks even if:

• values in steps 1 & 2 are hardcoded, so form group is valid from the beginning
• After reload on step 3, enter data in step 3 form group (so step 3 becomes valid, step 1 & 2 valid but not activated after reload) and trying to go to step 4 and it fails.
• if [editable] and [completed] are hardcoded to be true in MatStep

Same issue here

Any news here? Issue still exists and blocking almost any possible flow with url navigations, component UX looks inconsistent because of this

I have the same issue with the latest version too.

[lianbwl]

same issue here, is getting depressing to use Angular Material T_T

[maximilianbayerl]

ngAfterViewInit(){ this.stepper._steps.toArray()[0].interacted = true; }
setting previous steps as interacted did work for me

Hi!, Is anybody working on it? Otherwise, I could try to fix it if you don't mind.
