Stewart: Default Page template contains Content block in Query Loop causing issues editing individual pages

[jp-imagines]

Quick summary

The Stewart theme's default Page template places its Content block inside a Query Loop (with no inner Post Template block). As a result, when editing individual pages with the "Show template" setting active, you cannot edit the page's content because it is within a Query Loop.

Steps to reproduce

1. Activate the Stewart theme on your site.
2. From Pages (or Appearance > Editor > Pages), open a page in the editor.
3. If editing from outside the Site Editor, ensure the "Show template" setting is enabled. (From the right settings sidebar, under the "Page" tab, click on the Pages template name and then click Show template. This setting may be enabled by default if your account language is anything other than English (US); see 'Show Template' defaulting to on for non-English(US) languages wp-calypso#97494.)
4. Click on an element in the page's content area to select it.

A clear and concise description of what you expected to happen.

You should be able to select and edit content within the page as normal.

What actually happened

You cannot select or edit any of the page's content. Double-clicking shows a warning message:

You’ve tried to select a block that is part of a template, which may be used on other posts and pages. Would you like to edit the template?

Available workarounds?

Yes, easy to implement

If the above answer is "Yes...", outline the workaround.

The easiest workaround is to disable the Show template setting when editing pages. (Based on the discussion in the GH issue above, I understand that this setting is intended to be enabled by default.)

An alternate workaround is to edit the Page template to remove the Query Loop block (which must have its contents unlocked first).
