Details
This is the regular expression I wrote, which previously worked in the terser-webpack-plugin.
/^\**!(?! *(SuppressStringValidation|StartNoStringValidationRegion|EndNoStringValidationRegion))/i
I suspect that Rust's support for regular expressions isn't as extensive as JavaScript's.

Reproduce Steps
Add configuration:
minimizer: [
new SwcJsMinimizerRspackPlugin({
extractComments: {
condition: /^\**!(?! *(SuppressStringValidation|StartNoStringValidationRegion|EndNoStringValidationRegion))/i,
},
}),
],
Then run rspack build
