Maybe this is already fixed in the next version, but for the chance it is not the “mark” tag style in the markdown WYSIWYG editor is broken in dark mode at the moment.
There is not an internal file to edit the WYSIWYG style by any chance?
Also, as long as the stylesheet for <mark> does not state background-color: yellow; it is not detected by the md parser and just displays ==sometext== in the html preview.
It looks like there is a bug in the md parser.
The mark after a code fence is not detected.
==Algorithm Selection Sort==
\```
# julia
function selection_sort!(v::AbstractVector)
n = length(v)
for i in 1:n - 1
min_idx = i
for j in i + 1:n
if v[j] < v[min_idx]
min_idx = j
end
end
v[i], v[min_idx] = v[min_idx], v[i]
end
return v
end
\```
