Text between box drawing characters is rendered aliased (???) #6488
Description
When I run this in PowerShell (7),
"`e[30;47m`u{2500} What `u{2500}`e[m"
the text comes out without antialiasing. It looks like it's being drawn with FillGeometry just like a box drawing glyph.
If I flip the colors, it comes out antialiased.
To verify my theory that What was becoming part of the box drawing run, I put together a debug tool that turns glyph runs into graphviz documents.
Unfortunately, it doesn't look like it's so simple.
