Places autocomplete widget : bounds bias seems too weak - google-maps-api-3

Question

I want the Places autocomplete Widget to suggest places within France, but not restricted to France. I followed the official guide and added bounds (I set a rectangle bound that does not overflow outside of France), but the places returned for the first digits chars are most of the time out of the bounds.
I saw in the reference that the bound is biased and not restricted to the bound, but the bias seems too weak. Is there any way to make it stronger? (a parameter ?)
Example : https://codepen.io/benjamin-chevillon/pen/XBrNLZ :
new google.maps.places.Autocomplete(inputBounded, {
types: ["geocode"],
bounds: autocompleteBounds
});
When I type "33" for example, 4 of the 5 suggestions are out of the bounds. Whereas the widget restricted to France returns a lot of places with '33'.
On the official Google example, the autocomplete bounds is linked to the map. By default, the map is centered on Sydney. If you type "33" you'll get Australia's places. But if you move to France you will get European suggestions (but outside of France). I saw that it happens only when we start typing number. But it is a common way in France to describe a postal address.
I created an issue https://issuetracker.google.com/issues/111234226, but they redirected me on SO.

In order to restrict results of autocomplete widget to your bounds you have to use strictBounds parameter that was mentioned in issue tracker:
https://developers.google.com/maps/documentation/javascript/reference/3/places-widget#AutocompleteOptions.strictBounds
strictBounds - A boolean value, indicating that the Autocomplete widget should only return those places that are inside the bounds of the Autocomplete widget at the time the query is sent. Setting strictBounds to false (which is the default) will make the results biased towards, but not restricted to, places contained within the bounds.
So, your code should be rewritten as
new google.maps.places.Autocomplete(inputBounded, {
types: ["geocode"],
bounds: autocompleteBounds,
strictBounds: true
});
I hope this helps!
