🐛 [BUG] - Visual issue with SubNav underline

[stamat]

Describe the bug

SubNav items underline renders weirdly when the text breaks in two lines on "pre tablet" screen sizes. Making the span wrapper that contains :after underline display: block; position: relative; solves the issue.

.lp-SubNav li > a > span {
  display: block;
  position: relative;
}

Reproduction steps

On tablet screen sizes when there are a lot of items with a lot of text the underline misbehaves. The issue can be reproduced on https://github.com/features

Expected behavior

Underline spans full width of the SubNav.Item
