Cannot set thresholds on a new locale

[mansinarain]

Describe the bug
Trying to create a new locale and pass in thresholds such that '23 hours ago' would be '23h' and anything less than 24hours would not show up as days.

Code
`import dayjs from '@/js/be/dayJSPlugins.js';

const localeObject = {
name: 'en-segment',
relativeTime: {
future: 'in %s',
past: '%s',
s: '%ds',
m: '%dm',
mm: '%dm',
h: '%dh',
hh: '%dh',
d: '%dd',
dd: '%dd',
M: '%dM',
MM: '%dM',
y: '%dy',
yy: '%dy',
},
};

export function getRelativeTime(timestamp) {
dayjs.locale('en-segment', localeObject);
delete relativeTime.$i // this allow plugin to be installed again
dayjs.extend(relativeTime, {
rounding: Math.floor,
thresholds: [
{ l: 's', r: 60 },
{ l: 'm', r: 60 },
{ l: 'h', r: 24 },
],
});

return dayjs.unix(timestamp).fromNow();
}
`
