Exoplayer: Unable to change subtitle font size (Dash stream)

[islor]

Issue description

I've been trying to change the subtitle font size with the following code, but it does not reflect accordingly.
playerView.getSubtitleView().setApplyEmbeddedStyles(false); playerView.getSubtitleView().setApplyEmbeddedFontSizes(false); playerView.getSubtitleView().setStyle(new CaptionStyleCompat(Color.RED, Color.TRANSPARENT, Color.TRANSPARENT, CaptionStyleCompat.EDGE_TYPE_OUTLINE,Color.BLACK,null)); playerView.getSubtitleView().setFixedTextSize(TypedValue.COMPLEX_UNIT_PX, 100);

There is no issue with changing the style, but when it comes to font sizes I realise that the player is still taking into consideration cellresolution and rawViewHeight instead of the textsize I input.
Is this intended? If so why? and how do I change the font size?

Also, when testing with sideloaded subtitle sources it has no problem showing the font size I set.

Reproduction steps
