Enhance text editing experience on WindowsTerminal

[tusharsnx]

List of Issues/PRs that could further enhance text editing experience/rendering on Windows Terminal:

• Add support for Kitty/VTE extended underlines (4:x) [SGR] #7228 : Support for styled underlines, Eg. undercurl, dashed-line. ✅

  Left: Windows Terminal, Right: WezTerm(over ssh)

  

  ssh'ing bypasses ConPty and avoids the stripping of SGR 4:x VT sequence

• Investigate alternative ways to handle box drawing/block elements #5897 : After Implement cell size customizations #14255, if you change the default line height you might see gaps between BoxDrawing and BlockElement glyphs at the moment. ✅

  Left: Windows Terminal, Right: WezTerm

  

• Support coloring underlines independent of foreground text color: Done with Support rendering of underline style and color #16097 ✅

I'll add more if something's missing.

Do you have any links to reference docs for

Support coloring underlines independent of foreground text color: Currently same color is applied to both the text and the underline

Kitty allows setting the underline color: https://sw.kovidgoyal.net/kitty/underlines/

FYI, we were already kind of tracking the underline color as part of #7228.

Happy to close this. It took us less than one year to get all three together 😄
