[Mac] user caption styles not applied to correct element

• Component: Media
• Status: RESOLVED FIXED

[Eric Carlson]

User caption style overrides are not applied to same element used for the "cue" pseudo element, which makes it impossible to override styles applied by the page.

> +    m_fontSize = lrintf(smallestDimension * (document()->page()->group().captionPreferences()->captionFontSizeScale(m_fontSizeIsImportant)));

This is kind of confusing, that m_fontSizeIsImportant is modified by captionFontSizeScale().  Perhaps captionFontSizeScaleAndImportance(), and breaking up this into two lines?:

float fontScale = document()->page()->group().captionPreferences()->captionFontSizeScale(m_fontSizeIsImportant);
m_fontSize = lrintf(smallestDimension * fontScale);

>      if (m_textDisplayContainer)
>          m_textDisplayContainer->updateSizes(true);
> -    closedCaptionTracksChanged();
>  }

Could this be pulled into another bug? It seems unrelated.

And https://trac.webkit.org/r148058 for good measure.
