I've fixed it, but one reason is we point to the string containing the data from firstChild, but lastChild is unused:
| Offset | Size | Name | STRING | STR_EXT | NAME_STR | NAME_INT | INT | DOUBLE | OBJ/FUNC/ARRAY | ARRAYBUFFER | NATIVE_STR | FLAT_STR |
| 16b | | | | | | | | | | | FLASH_STR | |
|--------|------|---------|--------|----------|----------|----------|------|---------|----------------|-------------|------------|----------|
| 0 - 3 | 4 | varData | data | data | data | data | data | data | nativePtr | size | ptr | charLen |
| 4 - 5 | ? | next | data | data | next | next | - | data | argTypes | format | len | - |
| 6 - 7 | ? | prev | data | data | prev | prev | - | data | argTypes | format | ..len | - |
| 8 - 9 | ? | first | data | data | child | child | - | data? | first | stringPtr | ..len | - |
| 10-11 | ? | refs | refs | data | refs | refs | refs | refs | refs | refs | refs | refs |
| 12-13 | ? | last | nextPtr| nextPtr | nextPtr | - | - | - | last | - | - | - |
| 14-15 | 2 | Flags | Flags | Flags | Flags | Flags | Flags| Flags | Flags | Flags | Flags | Flags |
I think it's done because for names we use firstChild to point onwards so we can re-use the same freeing code, but if we did use lastChild it'd give us a little more room, potentially to allow >16 bit byte offsets which I know has been asked for
We had issues with ArrayBuffer not fitting in 12 byte systems: https://forum.espruino.com/conversations/392509/#comment17229419
