During noise synthesis, `libjxl` generates one batch of 16 floating point numbers for every partial 16-pixel wide row. After filling the row, it generates another batch of 16 floats for the stragglers, in case the the group width is not a multiple of 16 (which it isn't guaranteed to be, for exampl... | noise synthesis generates unused Xorshiro batch when noise group size is a multiple of 16 | https://api.github.com/repos/libjxl/libjxl/issues/1888/comments | 1 | 2022-11-10T17:02:56Z | 2022-12-02T12:31:54Z | https://github.com/libjxl/libjxl/issues/1888 | 1,444,257,921 | 1,888 |

**Describe the bug**
See, https://github.com/libjxl/libjxl/pull/1863#issuecomment-1305294301
In the Wikipedia.jxl when reading the image with coalescing turned off, we see images that appear are of duration 0 and appear to be empty.
