Since Navigator 4.5.5 suddenly there's an underline color when metadata is filled

hi there!

Since latest 4.5.5 release of the Navigator, all layers suddenly have underlines for techniques:

Before this new Navigator version, you only get an underline when you have filled in a comment. But now, it will also give an underline when having metadata.

I see this is done on purpose in this commit:
https://github.com/mitre-attack/attack-navigator/commit/bc4ad9fd105c9fa68c12e04a0505b60d3124c655#diff-e49d1d934cc9d96bce820fb261164a66e14c3c90fa2364ff83b6d12201992182

There's now a function getTechniqueUnderlineColor that determines the underline when this condition is true:
tvm.comment.length > 0 || tvm.metadata.length > 0 || this.hasNotes()

Instead of only when no comment is filled in (how it was before):
<span [style.border-color]="configService.getFeature('comment_underline') ? configService.comment_color: ''" [style.color]="getTechniqueTextColor()">

This change has a huge impact. It makes Navigator layers, and thus also the layers of users using DeTT&CT, significantly less attractive and hence less usable for presenting results. See examples beneath how it looks like when you create layers with DeTT&CT.

We propose to undo this change of underlining. Or give a possibility to influence this.

Start by inspecting the commit linked in the issue and the getTechniqueUnderlineColor function, then reproduce the underline behavior with metadata and with comments. Done means restoring the previous comment-only underline behavior or adding a way to control metadata underlines, with the affected Navigator presentation verified.
