Text inside MaterialTheme with only fontSize specified stopped working as before. It's caused by commit b4443bdb5e16dd90082451add9856171bc964888 with initial intent to mitigate another (documented) behaviour change about includeFontPadding. However, lineHeight is explicitly specified in MaterialTheme now, so after merging with explicitly specified parameters, it results in different line height behaviour.

Code Sample to Reproduce:

androidx.compose.material.MaterialTheme {
    androidx.compose.material.Text(
        text = "The quick brown fox jumps over the lazy dog.",
        fontSize = 72.sp
    )
}

Since similar behaviour already exists in material3, it's okay to keep it as-is, but it must be documented. Also, unlike includeFontPadding behaviour change, it affects not only Android, but all platforms of Compose Multiplatform.
