Hi Matthew. No worries :-).

I shouldn’t have used <sups>19</sups> as it’s too close to the HTML <sup>19</sup>, which is not what I meant.
I meant to say that the glyphs of the characters ¹⁹ U+00B9, U+2079 are at different height than the glyphs of 19 with the OpenType 'sups' feature applied.

<div style="font-family: Ubuntu; font-size: 70;">
<span>19</span>
<span>¹⁹₁₉</span>
<span style="font-feature-settings: 'sups' on; -webkit-font-feature-settings: 'sups' on; -moz-font-feature-settings: 'sups' on">19</span><span style="font-feature-settings: 'subs' on; -webkit-font-feature-settings: 'subs' on; -moz-font-feature-settings: 'subs' on">19</span>
<span><sup>19</sup><sub>19</sub></span>
</div>

As you say, it is expected that the HTML <sup>19</sup> would look different.

One might consider this a non-issue as both the superscript characters and the superscript OpenType glyphs are probably not going to appear next to each other.
