render-bug in vim's command input line

[christianparpart]

How it should look like:

Actual render

Or like in my case

The black should not be black but like the background color of the rest ;)

VT sequences for my case

"\e[?25l\e[27;75H:\e[2;8H\e[?25h"
"\e[?25l\e[27;75H \r\e[A:\e[25;48H\e(B\e[m\e[38:2:212:212:212m\e[48:2:0:122:204mCOMMAND -- <\e]112\007\e[2 q\e[26;2H\e[?25h"

Some better screenshot maybe (containing both lines in question)

plus debug output
