Store Editing Templates: Product Category doesn't load Product Archive as a fallback edgecase.

[tjcafferkey]

Describe the bug

There is a specific scenario where the Product Category does not load the Product Archive template as a fallback when it is eligible to do so.

To reproduce

Steps to reproduce the behavior:

1. Ensure you're running latest WooCommerce & WordPress 5.9 with TwentyTwentyTwo theme activated.
2. Make sure your block theme has a archive-product.html file, this will be used as the fallback template for Product Category/Tag templates.
3. In Settings > Reading set your Homepage to be the "Shop" page.
4. Start outside the site Editor in WP Admin (Appearance > Themes).
5. Now navigate to Appearance > Site Editor. Because your "Shop" is set as the homepage it should load the archive-product template here initially.
6. Now browse to "All Templates" to view the complete list of templates.
7. Scroll down to "Product Category" and notice how it correctly indicates it is from the theme.
8. Click into it to edit the template and notice how the template is empty.

Some things to note:

• If you refresh the page the template gets loaded correctly.
• If you navigate back out of the empty template, into different template and then back into the Product Category template it loads correctly.
• If you don't set "Shop" as your homepage this bug doesn't appear.
• The correct template data is present in the core redux store, even when displaying a blank template.
• If you have Gutenberg activated, when presented with the blank template if you switch between the Code Editor and Visual Editor (triggering a rerender) the template renders correctly.

This could be an issue within Gutenbergs Site Editor.

Expected behavior

• On step 8 the template should load correctly.

@tjcafferkey do you think this issue is the same as woocommerce/woocommerce#42656? Otherwise, should we reopen?
