- Open a window with a search box (Blueprint Library, Trains, Crafting, Research)
- Click the search magnifying glass twice (to show and then hide the text input field)
- Begin typing text and unexpectedly see that the items are being filtered by what your are typing
- Click the magnifying glass again and see the text that you just typed
This bug may be more noticeable if typing a letter to open a close a window (i.e. type 'e' to open the crafting window, click magnifying glass twice, type 'e' in confusion as the window isn't closing and items are being filtered).
I recorded a video at Google Drive link
