Reopening this issue, as the fix of adding 120px min-width didn't address i18n differences in "Add New Resource" string length:

Interestingly, after doing some more investigation we can see the same happens for the "Arches Designer" in languages where the terms "Resource Models" and "Branches" (mainly the former) are shorter than "Arches Designer". We don't see this in the English localisation, but a good example to see this issue is in Hebrew:

And lastly, in French we can see the same for "Map Layer Manager":

We can safely widen this issue to all navbar options which have sub-options (i.e. "System Settings", "Add New Resource", "Arches Designer", and "Map Layer Manager").
