Photos are not automatically marked for republishing

Question

I use Lightroom 5.2 and Photoshop CC.  I also use a number of publish services.  If I use Lightroom to edit a photo that has previously been published, it will be marked automatically for republishing.  If I use Photoshop to edit a photo that has been previously published (in this case a .PSD) and I select Edit Original to preserve layers in the file, Lightroom does not seem to recognize that the photo has been edited externally, and does not automatically tag the photo for republishing.  It happens this wal with all of the installed publish services.
Is this normal behavior, or have I inadvertently changed a Lightroom setting that prevents this from happening the way it should?  It's quite annoying, and I have convinced myself that previously it did not operate this way.

It may be worthwhile to list all those you tried, explicitly.
Here's how it should work:
If publish service has NOT overridden the default triggers:
--[[ Excerpt from SDK document:
    default: All built-in metadata that appears in XMP for the file. You can override this default behavior by explicitly naming any of these specific fields:
        rating
        label
        title
        caption
        gps
        gpsAltitude
        creator
        creatorJobTitle
        creatorAddress
        creatorCity
        creatorStateProvince
        creatorPostalCode
        creatorCountry
        creatorPhone
        creatorEmail
        creatorUrl
        headline
        iptcSubjectCode
        descriptionWriter
        iptcCategory
        iptcOtherCategories
        dateCreated
        intellectualGenre
        scene
        location
        city
        stateProvince
        country
        isoCountryCode
        jobIdentifier
        instructions
        provider
        source
        copyright
        rightsUsageTerms
        copyrightInfoUrl
        copyrightStatus
        keywords
    customMetadata: All plug-in defined custom metadata (defined by any plug-in).
    (plug-in ID).*: All custom metadata defined by the plug-in with the specified ID.
    (plug-in ID).(field ID): One specific custom metadata field defined by the plug-in with the specified ID.
(I assume develop settings are triggers regardless)
Each publish service is free to override the defaults, and some definitely do.
That said, I too believe there are bugs in this - I have the opposite problem: files are getting marked for republish which should NOT be.
One thing to note: editing the original should never mark for republish unless the original is in the publish collection. If you are actually publishing the edited tiff output from Photoshop, then that should be what's in the published collection, and if nothing has changed from a publish service point of view (e.g. ratings, keywords, ... - note: image data is not one of the items), it would be the "date created" which triggers it, so try changing that date and see if my theory is correct.
Hmm - it seems dateModified should be in there too, but it's not - hmm... (maybe that's the problem: date-created not changing (?))
