REG: Wrong font height of Noto Color Emoji

When running the text_emojo_zwj.qml Lancelot test with the recent dev branch of Qt, the height of each item is huge, and only three rows fit in the window.

Note that you may have to manually set the font to Noto Color Emoji, depending on the system. This is likely related to a recent change to fetch font metrics from OS/2 table when available.
