I need to get rects of part of the Text substing

Looking through TextLayoutResult I've found getPathForRange, it returns Path which is exactly what I need except I can't modify returned path. Perfectly I'd like to have a method to get list of Rects.

So I found getBoundingBox which returns needed rect only for a single character. And there I've faced a bug: right value of each last space in a text line is zero:

val text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod"

Text(
    text,
    style = MaterialTheme.typography.h6,
    onTextLayout = { layoutResult ->
        text.forEachIndexed { i, c ->
            println("$i $c ${layoutResult.getBoundingBox(i)}")
        }
    },
    modifier = Modifier.width(100.dp)
)

Console output:
