Strange behaviour with overlapping highlights

[LordBaryhobal]

There seems to be an issue with overlapping highlights.
For example:

Notice that for some reason, both highlights start at the beginning of the line and end at the end (though the line is longer than 9 characters). Additionally, the boxes and tags are not displayed in the correct order. The red Inner highlight should be inside the green Outer one.

Another strange case happens when both highlights end on the same character, causing the whole line to disappear completely:

This has been tested with Typst 0.15.0 and Codly 1.3.0

Full test file

#import "@preview/codly:1.3.0": codly, codly-init

#set page(
  width: 20cm,
  height: auto,
  margin: .5cm,
)
#show: codly-init

#let example(code) = {
  table(
    columns: (1fr, .6fr),
    table.header[*Code*][*Result*],
    raw(block: true, lang: "typ", code.text),
    eval(code.text, mode: "markup", scope: (codly: codly)),
  )
}

#example(````
#codly(
  highlights: (
    (line: 1, start: 1, fill: green, tag: [Outer]),
    (line: 1, start: 6, end: 9, fill: red, tag: [Inner]),
  ),
)
