[1.21.6 Bug] Overlay ctm tiles cannot be randomized using random ctm

[SeaOfPixels]

Description of Issue

Trying to randomize a ctm overlay texture using a separate random ctm properties does not work.

OptiFine Version

OptiFine 1.21.4 HD U J3, preview_OptiFine_1.21.6_HD_U_J6_pre1

Properties examples

The ctm overlay:

matchBlocks=dirt
method=overlay
faces=sides
tiles=<skip> <skip> <skip> <skip> <skip> <skip> snow_overlay <skip> snow_overlay <skip> snow_overlay snow_overlay snow_overlay snow_overlay <skip> snow_overlay <skip>
connectTiles=grass_block_snow
layer=cutout

The random ctm attempting to affect the ctm overlay:

matchTiles=snow_overlay
method=random
tiles=snow_overlay snow_overlay1

Overlay quads are not used in multipass and this intended, but it may be possible to change.
