Presumptive incompatible change in future edition erroneuosly listed

[ByteEater-pl]

The last point in B Additions and Changes That Introduce Incompatibilities with Prior Editions mentions the 9th edition.

The 9th edition will exist next June, and anything landed in master since the 8th edition is already in it.

I know. But it slipped into the standard published by Ecma. It either shouldn't mention the 9th edition or say that it's going to be corrected in it, not was corrected.

Conclusion: There is something odd going on; the original PR, https://github.com/tc39/ecma402/pull/471, is where the text in question originated, but how did the text get into Annex B without the corresponding change in SetNumberFormatDigitOptions?

@ryzokuken to investigate.
