The 'View webform submissions for own node' permission allows a role to view submissions, but the downloaded result set is empty

Problem/Motivation

A role granted the "View webform submissions for own node" permission at /admin/people/permissions can view webform submissions for their own node.

However, when downloading the submissions using the provided download functionality, the result set is empty.

Granting the "View any submissions" permission at /admin/structure/webform/manage/*/access resolves the download issue.

However, this permission also grants the role access to all webform submissions, regardless of the node, at /admin/structure/webform/manage/*/results/submissions, which is an undesired side effect.

It's important to note that the download functionality worked correctly in earlier versions. However, I cannot pinpoint the exact version where this issue began.

Steps to reproduce

• Create a webform
• Create a content type x that has a webform field
• Create a node of type x that uses the webform
• Grant "View webform submissions for own node" to a role
• Access the node as a user of the given role
• The results should be displayed properly however the download functionality should give an empty result set
