'Duplicate values for key' error

[jgclark]

/usr/local/bin/gather --url-open https://www.desiringgod.org/messages/the-battle-for-your-mind repeatably fails with error: "Swift/arm64e-apple-macos.swiftinterface:13885: Fatal error: Duplicate values for key: 'the' [1] 64997 trace trap /usr/local/bin/gather --url-open"

I get no errors when on a different page from the same site, e.g. "https://www.desiringgod.org/interviews/romes-seven-deadly-errors"

I believe this is a new problem report. Running gather-cli v2.1.6 on macOS 14.6.1.
