When editing a post, Phanpy allows me to edit the image descriptions / alt text, and shows the updated image descriptions in the compose box, but when I click Update, it warns me that images don't have descriptions (even though they do). It then doesn't save the image descriptions to the server.

• Which site: phanpy.social
• Which site version: 2024.08.31.1b8ab47
• Which instance: carfree.city

To Reproduce
Steps to reproduce the behavior:

1. Post a status with two images with no description
2. Edit the post
3. Click on each image in turn to see it blown up big, add descriptions and click Done
4. Click Update

Expected behavior
There should be no warning about missing image descriptions, and the added image descriptions should save.
