fails to detect bridge when using "detect overhangs walls" setting.

[KoenVanduffel]

Description of the bug

When using the "detect overhang walls" setting bridges that have a support on one side smaller than the wall thickness are not sliced as bridges. Switching "detect overhang walls" off generates bridges almost perfectly. The remining issue is that when one of the legs under the bridge is slimmer than the wall thickness the wall will be printed overhanging instead of making the wall slimmer and anchoring the bridge properly (this is an edge case though).

There are a few older bug reports that might be related: #12144, #11633, #11500, #10231, #9988

Simply switching "detect overhang walls" on and off will show the behavior.
