Como se llamas on front windows 100 series (1 Viewer)

This one has been gnawing on me for a while, so any help with answers would be greatly appreciated.

What are the plastic “nubbins” on the front window frames of my 99 LC for?
What are they officially called?
Thank you!

Toyota calls it a clip, but it’s technically a window guide to keep the glass in the tracks along the longest section of frame and window run that’s unsupported.
