Browsersync never loads after updating to gulp 5

[umbralOptimatum]

Issue details

After updating to gulp 5, Browsersync becomes unusably slow for my project. None of the images load, though the browser shows it still making requests. Looking at the networks tab, it's constantly making new requests for the same two images, about 50 new requests per second:

Downgrading to gulp 4 makes everything work again. No other direct dependencies were changed.

Steps to reproduce/test case

1. Update to gulp 5
2. ???

I'm not the one who set up Browsersync on this project, so I'm not sure exactly what's relevant. All of the other references are about the same: watching some directory, which starts a task that is ultimately piped to browserSync.reload({stream: true}).

const browserSync = require('browser-sync');

const dests = {
    base: 'build',
    assets: 'build/assets/',
    // ...
};

gulp.task('browserSync', () => {
    browserSync({
        server: {
            baseDir: dests.base,
        },
        ghostMode: false,
    });
    gulp.watch(srcs.assets, gulp.series('assets'));
    // ...
});

gulp.task('assets', () => gulp.src(srcs.assets)
    .pipe(changed(dests.assets))
    .pipe(gulp.dest(dests.assets))
    .pipe(browserSync.reload({stream: true})));
