No warning log message when trying to set invalid structure name

The bug

When trying to set an invalid structure name for a structure block by changing or setting its NBT (for example by using /data merge) the name is cleared. However there is no warning message in the log.

How to reproduce

1. /setblock ~ ~ ~ structure_block[mode=save]{mode:"SAVE",name:"[invalid"}
   

2. Open the structure block GUI
   → The structure name is empty
3. Check the log
   → No warning was logged
