quarto preview displays listing page instead of edited page when hot reloading

[mfisher87]

Bug description

Repro repo: https://github.com/mfisher87/sscce-quarto-preview-hot-reload-listing

Either use this repo to test, or find details below.

When editing a page that is part of listing, quarto preview will hot reload.

In Quarto 1.3.361 and prior, the edited page was correctly displayed after the hot reload.

In Quarto 1.3.427, the listing page is displayed instead.

Steps to reproduce

• quarto create-project --type website
• mkdir listing
• Create listing/index.md with barebones listing front-matter.
• Edit _quarto.yml to add a link to listing/index.md.
• Create listing/foo.md with barebones content.

Try the following steps with different versions of Quarto

• quarto preview
• Edit listing/foo.md, and write.
• The browser will refresh automatically. Is the test post displayed, or is the listing
  page displayed?
  • In Quarto 1.3.427, the latter is the case, which is unintuitive to me. In
    previous versions, the former is the case. I expect the page I edited to be
    displayed!

Expected behavior

When editing a page, triggering a hot reload by quarto preview, I expect to see the page I edited.

Actual behavior

If the edited page is part of a listing, the listing index is displayed instead of the edited page in Quarto 1.3.427.

I've made the fix to the 1.4 (main) branch and will back port to 1.3 branch for our next patch release, which is likely a couple weeks away. Thx for reporting this was an unexpected side effect and a great thing to fix.

[mfisher87]

Wonderful, thanks ❤️

If you drop me a ping/mention when the 1.3 backport is available, I'll get it released to conda-forge ASAP :)

[mfisher87]

Hey @dragonstyle is a backport release still planned? Thanks :)

[dragonstyle]

Apologies for the delay! Yes it should be coming this afternoon (within the next couple of hours). I'll update here when it is completed.

Apologies for the delay!

No sweat, I understand you're busy! Thanks very much, Charles :) I've got it on my list later tonight to open a PR on the conda-forge feedstock.
