Problem
As a user when I am automatically redirected away from a page, I see a toast but there is no way to return to the page I was redirected from.
Suggested solution
Primarily to service T146596: Make redirect into a toast message, toast messages can also carry actions. Pass url and label as 2 additional parameters to the Toast.show function.
Acceptance criteria
- When I visit https://en.m.wikipedia.beta.wmflabs.org/wiki/Obama I see a toast. When I click on that toast I am taken to https://en.wikipedia.beta.wmflabs.org/w/index.php?title=Obama&redirect=no
- Change the toast wording to make it clearer the toast is actionable. The new toast will still say (should be just a link per https://phabricator.wikimedia.org/T150189#5384918) :
Redirected from \"$1\"
but it should be accompanied by the action
Show redirect
Design

Developer notes
We want to make this a generic capability so future features can also make use of it
- The Thanks extension has a working example here: https://en.m.wikipedia.org/wiki/Special:MobileDiff/906429341
- When a toast has an associated action a 'show' label appears on the right hand side of the toast
- When clicking the toast action the user is navigated to that link ?action=edit&redirect=no
