Formatting adds unnecessary parentheses to long patterns with as captures #17796
Description
Summary
See this playground link, where I've put the expected formatting going in, and you can see the unexpected formatting coming out:
It appears that "grouping" characters in patterns like (), [], and {} aren't being used correctly when they are followed by a capture (as name). Instead of breaking on these, the entire pattern (including the capture) is wrapped in parentheses and indented.
