Image descriptions not working on Mastodon

Expected behavior

When entering an image description in the app, it should be transmitted to Mastodon (worked fine until recently).

Actual behavior

Image description seems to be omitted - it can't be viewed via mouseover in the web browser.

Steps to reproduce

Upload an image. Enter a description. Submit. View image details on Mastodon in the browser, or simple hover the mouse over it: Nothing.

Extra info

Another image description bug: If it ends with a blank like some autocorrect settings like to do, the Toot can't be sent at all.

I have to correct myself: I scrolled back and looked at all the images I uploaded where I'm absolutely sure I put in image descriptions. Whenever I posted with Twidere on Mastodon, there are none.

This is a huge issue regarding accessibility. Please consider fixing this. Not being able to use image descriptions is a deal breaker for me, and I otherwise really enjoy Twidere.

This is also a big issue for me. I have to use the (much clunkier) web version of Mastodon when I want to post images with descriptions.

Can also confirm I've encountered the same bug. Had no idea because the Twidere UI accepts an image description and I don't usually use the web client.

This is still an issue for me.

Adding image description in Twidere:

As you can see, the published toot has no alt text.

I vaguely remember someone made a fork that fixed this, but I am having trouble finding it at the moment; will edit if I find it.
