In order to do that we must change the text layer opacity to 1 but it has several implications: - the selection color must have an alpha component, - the background color of the span used for highlighted words must have an alpha component either, but now the opacity is 1 we can use some backdrop-filters in HCM making the highlighted words more visible. - fix a regression caused by #17196: the css variable --hcm-highlight-filter has to live under the #viewer element because in HCM it's overwritten by js at this level, hence links annotations for example didn't have the right colors when hovered.
