CRA5 - works:

CRA4 - glitch:

Clicking on the feature with weird softclip, can see that SEQ field is odd and has negative numbers in CIGAR

CRA4 - glitch:

CRA5 - works:

this bug actually leads to the page crashing in CRA4 in some cases due to an infinite loop in decode read sequence

create-react-app v5, nextjs, vanillajs, and vite demos not affected by this bug

This issue can actually be git-bisected so that it appears to have been introduced in 0a9370fd65c which coincided with the release of v2.2.0 https://jbrowse.org/jb2/blog/2022/11/04/v2.2.0-release/ which included the typescript-ified version of cram-js #3285

Unclear why that is the cause but is a clue
