Steps to replicate the issue (include links if applicable):

• Write a table with a style attribute that assigns a color, using {{#ifeq:}} block
• Press "Preview" to see your changes
• Save the edits

What happens?:
While I was trying to create a template on isvwiki, I encountered a rather interesting bug. Take this wikicode I made:

wikitext
<div align="center">
{| style="border: {{{obrub|{{#ifeq:{{{tip}}}|bystrostično|5|1}}px solid {{{kolor obruba|{{#ifeq:{{{tip}}}|bystrostično|#990000|black}}}}}}}}; background:{{{podklad|{{#ifeq:{{{tip}}}|bystrostično|#ffcccc|{{#ifeq:{{{tip}}}|odstraniti|#ffcccc|{{#ifeq:{{{tip}}}|ostrěgti|#ffcc99|{{#ifeq:{{{tip}}}|primětka|#99ccff|#cccccc}}}}}}}}}}}; padding-inline:1em; margin-block:1em;"
|-
{{#if:{{{ikona|}}}|! [[Fajl:{{{ikona}}}|frameless|57x57px|link=]] !}}! {{#if:{{{glavica|}}}|'''<big><u>{{{glavica}}}</u></big>'''

}}{{{tekst}}}{{#if:{{{zapiska|}}}|
{{!}}- style="font-size: 80%; text-align: left;"
{{!}} {{{zapiska}}}}}
|-
|
|}
</div><noinclude>
{{Dokumentacija}}
</noinclude>

This is what it looks like in the preview:
!preview

And this is what it looks like when saved:
!saved

Now, the difference in the saved and previewed version might be actually caused by a different bug (but wouldn't be bad to fix it as well), where if you're trying to do in-line table cells for a row with {{#ifeq:}} parsing, it breaks (like here):

wikitext
{{#if:{{{ikona|}}}|! [[Fajl:{{{ikona}}}|frameless|57x57px|link=]] !}}! {{#if:{{{glavica|}}}|'''<big><u>{{{glavica}}}</u></big>'''

and I've already quite verified to be independent. It's easy to work around it tho. But the most prominent bug is the detached context one, where any option that starts with a special character (like the pound symbol # that's used for numbered list), it gets treated as wikitext of a separate context and rendered as that.

The reason why it doesn't render the border color as numbered list is that the default value is actually the word "black", which gets treated normally, and therefore is part of the style code. But once I've actually introduced the keyword into the mix, sure enough, the border color gets treated as wikitext again and renders as a numbered list.

When I introduce those values as direct template arguments for overrides, they are rendered normally.

What should have happened instead?:
I would have expected something like this:
!correct behaviour
