Important HTML elements need to have their tabindex attribute specified which will allow you to tab into each one sequentially. Without tabindex the browser may auto-detect tabbable-elements, but it will be inconsistent from browser to browser or may not work at all especially depending on the complexity of the page's HTML, CSS, JavaScript, IFRAMES, etc.

More info: https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/tabindex and https://www.w3schools.com/tags/att_global_tabindex.asp

Here's two examples of navbars with dropdowns with and without the tabindex attribute specified and works as expected (at least on macOS Safari and Google Chrome)

<div class="navbar-item has-dropdown is-hoverable" tabindex="1">

Also know that each navbar-item inside that the dropdown will also need their own tabindex attribute to allow you to tab into each one and the above example I also added tabindex="2" through tabindex="5" to allow for that.
