Alas, GitHub has been plagued by bugs and UX regressions year after year.
I reported a bug last year about being unable to quote code blocks. It's quite a basic yet fundamental feature, right? They acknowledged the bug and moved on. To this day, quoting a block of code is still broken [1].
They simply don't care. I suppose their attention is focused on other subjects...
Anyway, I kind of accepted the "enshitification" of things I used to like. Fortunately, in this case, we can still hack our way around using custom userscripts [2].
They completely redesigned the code navigation to load it dynamically using React. One of the regressions introduced caused the entries to be duplicated when searching for a word using Ctrl+F. Their solution to address this issue? Decompose the source character by character, assigning each individual character its own distinct HTML node...
Needless to say, in addition to abysmal performance (it took seconds to display on my laptop), this also caused new problems (such as the inability to search for certain composite emojis). The worst part is that they seemed proud of their hack, since they wrote a blog post about it.
Here is the ticket opened by @retr0id: https://github.com/oven-sh/bun/issues/28030
And here is the swarm of bots / LLMs / agents that open, review and bikeshed the PR before it's closed by the stalebot: https://github.com/oven-sh/bun/pull/28031
It's hilarious. But also a little sad.
