Conversation
When flip: true, the brace is drawn pointing in the opposite direction, but the spike and content anchors were always positioned using positive amplitude values. This caused labels to appear on the wrong side of flipped braces. This fix multiplies both amplitude and content-offset by -1 when flip is true, ensuring anchors are positioned correctly on both normal and flipped braces.

Problem
When
flip: trueis set on a brace, the brace is drawn pointing in the opposite direction, but thespikeandcontentanchors were always positioned using positive amplitude values. This caused labels to appear on the wrong side of flipped braces.Solution
This fix multiplies both
amplitudeandcontent-offsetby -1 whenflipis true, ensuring anchors are positioned correctly on both normal and flipped braces.Related Issues
This is similar to the fix for
flat-bracein PR #688, but applies to the regularbracefunction which was not included in that fix.Testing
Tested with both horizontal and diagonal braces, with and without flip. Labels now correctly position on the appropriate side of the brace in all cases.
