analyzePartial broken?

[dgmltn]

It appears that perhaps something is wrong with snapshots or analyzePartial. The first test here fails, and the second one passes by avoiding using snapshots altogether. (The second appears to be the way that KodeView is working currently).

    @Test
    fun basic_getHighlights_location() {
        val highlighter = Highlights.Builder()
            .language(SyntaxLanguage.JAVASCRIPT)
            .build()

        highlighter.setCode("const foo = 'bar';")
        val highlights1 = highlighter.getHighlights().filterIsInstance<ColorHighlight>().sortedBy { it.location.start }
        highlights1.size shouldEqual 4
        highlights1[0].location shouldEqual PhraseLocation(start=0, end=5)
        highlights1[1].location shouldEqual PhraseLocation(start=10, end=11)
        highlights1[2].location shouldEqual PhraseLocation(start=12, end=17)
        highlights1[3].location shouldEqual PhraseLocation(start=17, end=18)

        highlighter.setCode("const foo = 'barrr';")
        val highlights2 = highlighter.getHighlights().filterIsInstance<ColorHighlight>().sortedBy { it.location.start }
        highlights2.size shouldEqual 4
        highlights2[0].location shouldEqual PhraseLocation(start=0, end=5)
        highlights2[1].location shouldEqual PhraseLocation(start=10, end=11)
        // FAILS HERE:
        highlights2[2].location shouldEqual PhraseLocation(start=12, end=19)
        highlights2[3].location shouldEqual PhraseLocation(start=19, end=20)
    }

    @Test
    fun basic_getHighlights_location_alt() {
        var highlighter = Highlights.Builder()
            .language(SyntaxLanguage.JAVASCRIPT)
            .build()

        highlighter = highlighter
            .getBuilder()
            .code("const foo = 'bar';")
            .build()
        val highlights1 = highlighter.getHighlights().filterIsInstance<ColorHighlight>().sortedBy { it.location.start }
        highlights1.size shouldEqual 4
        highlights1[0].location shouldEqual PhraseLocation(start=0, end=5)
        highlights1[1].location shouldEqual PhraseLocation(start=10, end=11)
        highlights1[2].location shouldEqual PhraseLocation(start=12, end=17)
        highlights1[3].location shouldEqual PhraseLocation(start=17, end=18)

        highlighter = highlighter
            .getBuilder()
            .code("const foo = 'barrr';")
            .build()
        val highlights2 = highlighter.getHighlights().filterIsInstance<ColorHighlight>().sortedBy { it.location.start }
        highlights2.size shouldEqual 4
        highlights2[0].location shouldEqual PhraseLocation(start=0, end=5)
        highlights2[1].location shouldEqual PhraseLocation(start=10, end=11)
        highlights2[2].location shouldEqual PhraseLocation(start=12, end=19)
        highlights2[3].location shouldEqual PhraseLocation(start=19, end=20)
    }

    private infix fun Any?.shouldEqual(expected: Any?) {
        assertEquals(expected, this)
    }

Hi, thanks for that.

After your test I am not able to tell what's wrong. I will need a closer look
