"F" button not working on mining designations when another window is pinned

I did accidentally delete a part of my buried pipes. I clicked on the existing pipe and pinned it to see where I should dig down to reconnect it. I noticed that the F button to switch from flat to ramp mode doesn't work in the mining designation when the pipe was pinned. I could still click on the slope toggle with my mouse. Q and E still works to toggle height of the mining designation. Very minor issue but part of the game polish 🙂

Update: I realized that the F button does rotate the pipe in this situation. I realize that it's quite the niche situation, but maybe it could either be communicated somehow (pop-up text maybe?) or the mining designation could take precedence over the pipe?

Looks like theyve gotten this one fixed in experimental.
