If this issue only occurs in one browser, which browser is a problem?

Describe the Bug

I have the following line in src/content/blog/markdown-style-guide.md (line 42):

![](../../assets/blog-placeholder-about.jpg)

I would expect that to output an img tag with an empty alt attribute (alt=""), but it actually doesn't output any alt attribute at all -- it's completely missing from the img tag.

I found this issue but it appears to have been resolved back in 2022, so it looks like the issue has resurfaced.

What's the expected result?

![](../../assets/blog-placeholder-about.jpg) in markdown content should render an img tag with alt="".
