The issue is present on mobile for the following scenarios (see the details In Steps)

• deleting Template
• deleting wikifunction
• deleting table
• deleting reference list

Steps to replicate the issue :

• start editing an article that has a template, e.g. https://test.m.wikipedia.org/wiki/MavetunaZialnt30_2 has both a template and a wikifunction.
• click on one of the article's templates so the dialog (ve-ui-mobileContext-menu) appears

What happens?:

• click on the Delete option (precisely on the label 'Delete") - the Help overlay will appear (see the gif below) the gif is about wikifunction dialog but the same issue is present with the template dialog:
  

What should have happened instead?:

• the Help button should not be clickable if it's not visible

Software version : the issue is present on wmf.6

Notes

• the issue is also present on the following VE insert options
  
  (1) Insert table - this case is especially severe since an inserted table on mobile can be deleted only via the source editor.

• Clicking on 'Delete" icon doesn't produce any actions
• Clicking on X brings up the Help panel overlay and the Console error
