@mroeschke @jorisvandenbossche Matt, interested on your views on how this should behave today with the "arrow dtypes" and Joris on the future of Decimal types (or other new numeric-like types)...

@Vernon-codes there is already a PR open to address this issue #61659

The behavior on main has changed since this issue was opened https://github.com/pandas-dev/pandas/pull/47793#discussion_r925067971 ``` 1.5.0.dev0+1176.gf7e0e68f34 ['1', , '3'] Length: 3, dtype: string A 0 1 1 2 3 ['1', , '3']...

> I'll bisect to confirm where fixed, but assuming #47763 can confirm. fixed in commit: [1b1dd36016bbf0b216d654b84d62a005fa5b48a0] BUG: fix regression in Series[string] setitem setting a scalar with a mask (#47763)

Thanks @COderHop for the report. It appears that you have a good grasp of the issue. IIRC this has been reported/discussed before but I can't find it at this time....
