There are no bugs with link_preview_options in Bot API. show_above_text works correctly in InlineQueryResultArticle. TDLib-based apps like Unigram or Telegram X immediately show the message correctly for the sender. Android app shows it correctly after the message is sent and the chat is reopened. Telegram Desktop shows it correctly after app restart. You can create an issue for specific app at https://bugs.telegram.org/.
in InlineQueryResultArticle it always shows me the "expired" image.
This is intended behavior. Content of URLs is cached for a long time. You can't expect Telegram to redownload all files sent by URLs all the time.

It seems you didn't get it right.
Static URL without "&expires=xxx"

Dynamic URL with "&expires=xxx" that changes each request

Sankaku Channel refuses to show an image and redirects to "expired" if you change anything in the URL or if you have a bad User-Agent.

So this is Telegram servers issue?

All photos are fetched from the specified URL by Telegram servers. But if the site returns "Expired link" to any request with Telegram's User-Agent, then there is no issue.

May there be a chance that telegram-bot-api edits link_preview_options URL when it's used in InlineQueryResult?

No, URL is passed exactly as provided to the server.

- Let's imagine that we have a ~4gb file, and a premium subscription on the account. So we are trying to upload the file using preliminary wrappers, we do perform the request, wait until the file is loaded, and chunk are saved on the server-side/cdn whatever, close the database, then we open it again, let's say 10 minutes later, we are trying to upload it, but due to the tdlib cache we just run into a weird situation where the filds 'is_uploading_active' are being set as true in the response to the original 'preliminaryUploadFile', even though the file is already uploaded and the uploaded_size matches the size, and expected_size fields values, while 'is_uploading_completed' is being set to false.
