Some fonts (at least FreeType fonts) specify the non-zero width of `Zero Width Joiner`, `Zero Width Non-Joiner`, and `Zero Width No-Break Space`. Later, during the rendering, these glyphs are skipped causing the `InlineTextBox`es to become wider than they should be. 1927443 1 vitaly 2023-01-23 06:46:58 -0800 Pull request: https://github.com/WebKit/WebKit/pull/8973 1929376 2 webkit-bug-importer 2023-01-30 06:39:16 -0800 <rdar://problem/104819130> 1929710 3 ews-feeder 2023-01-31 01:53:20 -0800 Committed 259618@main (f7b4df2d3a2c): <https://commits.webkit.org/259618@main> Reviewed commits have been landed.
