      Noticed when testing MDLQA-18233. Should be a relatively simple fix too. I didn't test with LTI 2.0 forms when I added this feature, so shame on me really (but we should also drop LTI 2.0 support given it's long dead now...)

      To replicate:

      1. Create 2 Moodle sites - platform and tool
      2. Set up an assignment on the tool site and publish it as an LTI tool , using the "Legacy LTI (1.1/2.0)" tab, and take note of the "Registration URL")
      3. In the plaform site, go to "Site admin > Plugins > Activity plugins >External tool > Manage tools"
      4. Enter the Registration URL you copied earlier
      5. Click "Add legacy LTI"
      6. Continue through the registration process and activate the tool
      7. Edit the tool by using the cog in the tool card
        Expected: No warnings are shown
        Actual: You see the following warnings:
