Hey y'all,
This feels like such a weird thing that it must be only happening to me, but since it reproduces for different versions of both dplyr (1.0.10 and 1.0.99.9000) and different versions of RStudio (2022.07.2 Build 576 and 2022.02.3 Build 492.pro3) I figured I'd ask here at the risk of looking rather silly 
Basically, pressing tab for auto-complete doesn't work for dplyr join functions for me, except for the first two arguments; x and y, when not piping; or y and by when piping. After that the code-completion suggestions (and auto-complete) don't work (image a), unless I first delete the closing parenthesis (image b) or forget a comma (image c)
The following screenshots show what happens when pressing tab:

c)
This doesn't reproduce in any other functions I've tried (see image d for example)
d)
Any ideas why this is happening and what I can do to fix it?
