Below is an example of the bug, it started a while ago.
Whenever I start typing an entry, formerly it would start filtering a list of autocomplete suggestions after each character type, making the list smaller and smaller. This was good for me, because I could get to the information quickly. Now, it seems like the mechanism changed, where it registers only the first letter I type (in the example case it’s ‘b’), if I erase it without leaving focus of the cell and start typing other stuff, the dropdown just gets stuck in the suggestions for the first letter always.
