Summary
hCaptcha will be required for all DiscussionTools edits on WMF wiks and so to avoid a double-submit for the user we should render the hCaptcha CAPTCHA widget before the user makes their first edit attempt via the tool
Background
- On WMF wikis, hCaptcha will be required for all edits
- This means that several interfaces (like VisualEditor) have been updated to show the hCaptcha CAPTCHA widget before the first edit attempt when all edits need hCaptcha
- Knowing if all edits require hCaptcha is done by checking if hCaptcha is needed to edit the current page without including any content in that check
- The result of this is available through the mw.libs.confirmEdit.CaptchaWidget.static.captchaNeededForEdit method, which returns the type of CAPTCHA needed to make a "generic" edit (a generic edit represents that any edit to the page would need a CAPTCHA, ignoring any extra rules that may be based on the content of the page or the newly added content)
- We should make DiscussionTools render the CAPTCHA widget if we know that it would be required for a "generic" edit
- Some CAPTCHAs need specific data that is only returned after a failed response, such as #fancycaptcha. This means that we should for now only make DiscussionTools render the CAPTCHA if the CAPTCHA type is hCaptcha (as this can be rendered without having first attempted to make the edit)
Acceptance criteria
- DiscussionTools renders the hCaptcha CAPTCHA before the first edit submission attempt if hCaptcha is required for a "generic" edit
