Wrong symbols in Unicode:So layer

What steps will reproduce the issue?

1. Use Jetbrains Mono
2. Type ⊞ or ⊠ (Unicode code points \u229E for plus box and \u22A0 for times box)

What is the expected result?

Font glyphs that look like a boxed plus and a boxed times symbol.

What happens instead?

Font glyphs are swapped: boxed plus where unicode standard specifies boxed times, and vice versa.
