Spectrogram labels when scrolling

[Brabudu]

It would be useful to be able to choose, in case of scrolling, if the labels of the spectrogram should move with the spectrogram or be fixed (css position: fixed). Thank you

@Brabudu You ask for the possibility to choose between fixed and absolute, but to me the current 'fixed' behaviour just seems like a bug - I can't think of a use-case where this would be the intended behaviour. I've submitted PR #2558 that would just always make it absolute.

Do you have a use-case in mind where 'fixed' would still be required?

For others finding this issue: a temporary work-around before the PR is merged can be achieved with the following CSS:

spectrogram .spec-labels {
  position:absolute !important;
}
