Missing required column / checkbox when no components present [#2649042]

On a clean Drupal 7.41 installation with only webform-7.x-4.12 installed, I witness a strange behavior when adding components.

When no component is present, the required column is absent (see screenshots).

This might be related to the following:

Any ideas?

This issue is the manifestation of the following bug in Drupal core:
#997370: Tabledrag is not hiding the correct columns

@thlor: The issue you mention is D8 while I'm experiencing this in D7... the discussion over there pointed to #988930: Sticky table headers need to react properly to "show/hide weights column" link which was committed do D7 core some time ago.

Therefor, I think this issue is specifically related to webforms 7.x-4.12 and not D7 core.

I remember the bug not being present in previous versions of webform 7.x-4.x so I tried 4.11 and the bug went away. By comparing the two versions, I suspect something is going on inside template_preprocess_webform_components_form and _webform_components_form_rows with the 'Form key' column that was added there.

Marking this as Active again...
