Pull request overview
Fixes an issue where replacing callback_data in InlineKeyboardButtons (when arbitrary_callback_data is enabled) drops other button attributes by cloning the original button before mutation.
Changes:
- Update
CallbackDataCache.process_keyboardtodeepcopybuttons before updatingcallback_data. - Extend the callback data cache test to assert preservation of non-
callback_dataattributes. - Add an unreleased changelog entry for the fix.
