Make HAML scrollable tabs consistent with GitLab UI scrollable tabs
Related to #345699
Currently scrolling tabs are implemented in the GitLab UI GlTabs
component and in HAML using app/assets/javascripts/layout_nav.js#L38. However, these two implementations function differently:
GlTabs
component
GitLab UI - Left and right arrows that are clickable.
- Can't scroll left and right, must click the arrows.
HAML version
- Left and right arrows that are not clickable. They are only used to indicate that there are more tabs.
- Must scroll left and right to see hidden tabs.
