Accessibility issue: Reflow at 400% zoom prevents user from reading the text in the search field

Describe the bug
Hi guys. As part of a recent accessibility test on one of the GeoNetwork instances of one of our clients, it has been reported to us that when zooming to 400% the text within the search input is unable to be seen in full.

I tried to look into resizing this, but I didn't manage to find an elegant way that doesn't break the layout, do you have any idea how this can be fixed? Any help would be massively appreciated 🙏

To Reproduce

1. Navigate to the search page
2. Zoom at 400% (in 1280px wide viewport)
3. Observe the search bar behaviour

Expected behaviour
