Checked both cases described in the task - both cases do not present any issues. Some additional testing also did not find, so far, any issues.

(1) Returning to an article after discarding Add link recommendation layer

a) Special:HomePage → get to the Add link article via Homepage → interact with Add link inspector → do not save → click on User name link to go Homepage → and return to the same article again via Homepage

b) Special:HomePage → get to the Add link article via Homepage → interact with Add link inspector → do not save → click on Read (do not navigate away!) → switch to VE
The Add link recommendation overlay would load successfully without double icons and any additional warnings.

(2)

Relatedly, if you navigate away or close the tab after making a change, then try to start a normal VE session on the article, you'll get an error saying your changes could not be recovered (this failure is presumably because the DmRecommendedLinkAnnotation class isn't loaded).

Special:HomePage → get to the Add link article via Homepage → interact with Add link inspector → do not save → navigate away → search for the article and click on VE

Normal VE mode will load successfully.

The issue re-appeared around April 16 - I have the screenshots of that date. Although I believed the steps to reproduce the issue were somewhat different.

Re-checked - the issue is not re-producible.

• any changes to the context items or made in the source editor won't be saved when a user navigates way
• the standard browser warning will appear
• returning to a previously edited in Suggested mode article via SE module or, if a user did not leave the page, from Read mode to Edit again - won't display double icons.
