Background

We would like to be able to prompt users to add alt text to images in an article after they have finished an edit on that article. Many users within the app edit sections, and others edit using the "Edit source" option. If we pull the wikitext for the edit the user has just completed, and that edit is a section edit, we will not have the full wikitext for the page. If that section did not have an image, they will not be eligible for the experiment. This could limit our number of potential users in the experiment, if most editors are editing using the section editing.

Requirements

• Suggest an image to add alt text to for users who edited a section, even one that does not contain an image
• Pulling the full wikitext should not cause a signifcant delay in the display of the Alt text modal.
