Ran across this while examining T573.
Holding right shift to display entity info for that block near certain edges of planet plates fails to show the information.
This is not related to unitialized blocks as adding and removing blocks from non displaying areas is not prevented.
Using right shift in astronaut mode seems to be unaffected and the behavior is only in the plates buildmode, however, attempting to use right shift in astronaut mode while zoomed out (3rd person view) will show no info at all.
Tested on official test server in sector 4,-15,26
