Something funky with Admin plugin and Shortcodes

[Perlkonig]

Moved from here at @rhukster 's request.

I have a couple of shortcode plugins. I've received bug reports for Scheduler and Table Importer. It seems related to the Admin plugin somehow. I've done the following:

1. I did a clean install of Grav only (no Admin).

2. I then did bin/gpm install table-importer.

3. I replaced default.md with the following and dropped in import.csv.

---
title: test
---

[u]Testing[/u]

[ti file=import.csv /]

3. It works as expected.

4. I then downloaded and installed Grav+Admin and immediately did bin/gpm install table-importer.

5. I added some dump() statements to table-importer.php.

6. I then dropped in the exact same markdown and csv.

7. It fails.

So it appears the onShortcodeHandlers isn't getting called for some reason, but the [u] code is working. Any ideas?
