Jetpack Post by Email feature: numeric-only tags are not processed correctly

[alinclamba]

Impacted plugin

Jetpack

Quick summary

Numeric-only tags (e.g., [tags 3322]) are not processed correctly in the Post by Email feature. Alphanumeric tags (e.g., [tags pp3322]) work as expected.

Steps to reproduce

1. Enable the Post by Email feature
2. Compose an email and include a numeric tag (e.g., [tags 3322]).
3. Send the email to be published.
4. Check the post once published and see that the tag is not displayed
5. Compose another email
6. Add an alphanumeric tag this time (e.g., [tags pp3322]) and send it.
7. Check the post published and see that the tag was correctly processed and displayed

This is due to this:

jetpack/projects/plugins/jetpack/json-endpoints/class.wpcom-json-api-update-post-endpoint.php

Line 409 in 9e3ae2f

* Consequence: To add a category/tag whose name is '123', the client must

The PBE processor takes the tags in the shortcode and passes them to the v1 WP.com new post endpoint, which accepts tag names or tags ID. If it is numeric only, it assume it is a term ID.

We'd need to either change PBE to take a numeric tag and look up the corresponding term ID, using that instead, when passing it to the API or something with the endpoint.
