12:00 time (noon) displays incorrectly when using en-GB format

[rdtome]

Reporting a bug?

Hello.

Using Chrome, we've noticed an incorrect display of time at noon when using "en-GB" format.

A date like 01/01/2023 12:00 is displayed as 01/01/2023, 0:00 pm when it should be displayed as 01/01/2023, 12:00 pm

The time displays incorrectly when using Chrome ( 0:00 pm ) but displays correctly when using Firefox ( 12:00 pm )

I have written some code that illustrates the problem. You can access it here :
https://codesandbox.io/s/vue-i18n-9-template-forked-s686nz?file=/index.html
Run it with both Chrome and Firefox to compare the display of the second date with the different time formats.
The bug happens when displaying in Chrome using "en-GB" format.

Expected behavior

Using Chrome, a date set to noon, displayed in "en-GB" format should display like this : 12:00 pm

Reproduction

Using Chrome, a date set to noon, displayed in "en-GB" format displays like this 0:00 pm instead of 12:00 pm

You can reproduce with this code :

System Info

Noticed while running recent up-to-date copies of Chrome, under Windows11

Screenshot

Chrome with en-GB, the second date (midday) displays incorrectly :

Other formats "en-US" or "fr" display correctly :

Not sure why, but i18n doesn't seem to work in the demo right now. I've tested on Chrome and Firefox, and I've also downloaded the demo and tested it locally in Chrome and Edge. Every testing session gives me
