Summary: Wrong baseline for fall-back font Noto Emoji
Key: FOP-3175
URL: https://issues.apache.org/jira/browse/FOP-3175
Project: FOP

I have a text with the Emoji glyphs.
In the fo:root I've set two fonts - Times for the main text and NotoEmoji
(Google font) for the glyphs which missing in the Times.
{code:xml}
font-family="Times, NotoEmoji"
{code}
The sample text is very simple:
{code}
text ✔ text
{code}
The FOP substitutes the 'check mark' glyph from the font NotoEmoji properly,
but the glyphs shifted up (look like the wrong baseline):

I've tried to specify font-selection-strategy="character-by-character" - the
same result.
But if I specify the font NotoEmoji explicitly for the 'check mark':
{code}
<fo:inline font-family="NotoEmoji">✔</fo:inline>
{code}
then 'check mark' glyph renders in the one line with main text:
