When switching chat folders by tapping a folder tab that is not adjacent to the current one (for example from the first folder to the third), the chats of the folder in between flash on screen for a split second during the transition. While they flash, the texts of both lists render on top of each other at full opacity, producing unreadable overlapping text (see attached screenshot). This happens in both directions (folder 1 to 3 and folder 3 to 1) with a single tap, every time. Switching between adjacent folders animates normally.
Expected: the list should animate directly to the tapped folder without rendering the chats of the folder(s) in between.
Reproduced on Telegram iOS 12.9.2 (34474), iPhone 16, iOS 26.5.2.
Steps to reproduce
Create at least 3 chat folders (Settings > Chat Folders), each with a few chats that have text previews.
On the chat list, open the first folder tab.
Tap the third folder tab (skipping the second one).
Look at the chat rows during the transition: the rows of the skipped folder flash with their text overlapping the incoming list (attached screenshot).
Repeat in reverse (third folder back to first): same result.
