Tiny Rails papercut that kept bothering me:
Sometimes I want pluralize to pick "person" vs "people" without the count.
So I opened a PR for:
pluralize(2, "person", count: false) → "people"
Just me, or have you needed this too? 😅

I understand why it happens now.
I just don't understand why #Rails does that 🤔
Is this on purpose or should both environments report the same error when an error occurs in a view?
Either ActionView::Template::Error or the unwrapped NoMethodError

As of phlex-rails 2.1, ViewComponent, ActionView and Phlex all share an output buffer so the cost of switching back and forth during a render —even thousands of times— is very low too.

Somehow one of the ActionView helpers is overriding the capture method on the component so when Phlex calls capture, it doesn’t work.

looks like `ActionView::Helpers::AssetTagHelper#video_tag` still doesn't support setting tracks, so I guess if you're using Rails, you gotta write the HTML yourself if you want subtitles on a video. 😩
