History entry for modals

[hardl]

When opening a modal micro frontend and showModalPathInUrl is true (https://docs.luigi-project.io/docs/navigation-parameters-reference/?section=showmodalpathinurl), a browser history entry should be created, so that if the user does a history back, the modal is closed but the main mfe will stay the same.

need some discussions

Blocked because behavior not yet clarified.

[hardl]

when opening a modal with showModalPathInUrl, store the history length and create a history entry (i.e. using pushstate). when closing the modal, go back in history to the stored state. Double check "re-visit" behaviour, e.g. after page refresh or deeplink with no history.

tbd: history.go and history.back are async

[JohannesDoberer]

Add a popState eventListener when calling history.go() and use the option parameter to use it once.

• call pushState
• (go forward)
