spec: Does Block_Maximum_Size apply for RAW/RLE blocks?

Describe the bug

While fuzz testing my Go port, I came across this input that I can decompress, but cli cannot.

The input has an RLE block of 1572321 bytes. The cli fails with Destination buffer is too small and extended error is check regenSize > dstCapacity failed, returning ERROR(dstSize_tooSmall).

Reading spec I want to confirm my (new) reading is correct;

Does the Block_Size is limited by Block_Maximum_Size (see below) mean that no matter the block type, the limit of Window Size/128KB applies? I kind of read/assumed that other types could use up to the 21 bits available.

Indeed,
the Block_Maximum_Size is applicable to all block types, including RLE and RAW.

Thanks. Just wanted to confirm before adding the restriction locally.
