//As a Watchlist Expiry user, I want the star to be automatically updated when I make a watch period selection via edit, so that I can immediately see the relevant watch period in the star (shading & tooltip).//
NOTE: This issue is most likely related to T256654. It is also sometimes reproducible and sometimes not on various environments (i.e., there is not necessarily a consistent history of this bug).
**Acceptance Criteria:**
* If the user watches via legacy source editor (temporary or permanent), the star and tooltip should be automatically updated upon saving changes
* If the user edits a temporary watch period via source editing, the star and tooltip should be automatically updated upon saving changes
* If the user unwatches via source editing, the star and tooltip should be automatically updated upon saving changes
* Investigate/fix the issue in T256654
Steps to reproduce:
# Use the legacy wikitext editor
# On a page not on your watchlist (new page, or existing page):
## Edit the page, include any change in your edit
## Select "watch" using the 'watchthis' control check box
## Publish the page
# The page now opens for reading, however the watchlink or star still reports the page is not watched
Desired behavior: when the page re-enters reading mode, the now-current watched status should be used to display the appropriate tab controls
Note: the page does actually get added to the watchlist, and manually reloading the page will correct the display
