The PR template's untouched "Depends on: <!-- #PR, or none -->" line
matched the checklist regex, so prose such as "Depends on #1400" was never
consulted and the declared dependency was lost. HTML comments are now
stripped and the prose form is used when the checklist line is blank. An
explicit "Depends on: none" still takes precedence.
