Original GitHub issue: https://github.com/rivo/tview/issues/1126

Demonstrated by the following go snippet:

buffer := bytes.Buffer{}
writer := tview.ANSIWriter(&buffer)
writer.Write([]byte("\033[1;0m"))
fmt.Println(buffer.String())
// output: [::b]

See https://go.dev/play/p/_yXZTydD9YL

The expectation is that it would reset all attributes due to the final 0;. So it should result in either [-:-:-] or at least [::b][-:-:-]. This is how it works in other terminals.

The effect is that something like \x033[1;32mtest\x033[1;0m causes all remaining text to be printed as green as well, while in terminals, and gitlab log output, all attributes are reset and the remaining text is printed normally.
