On this diffs page, there are three documented instances where a map-banner on hiwikivoyage, bnwikivoyage, trwikivoyage has different heading styles on Parsoid.
On inspecting the HTML differences, it looks like Parosid's HTML didn't get the new section link treatment.
Legacy HTML:
<div class="mw-heading mw-heading2"><h2 id="विकियात्रा_पर_आपका_स्वागत_है">...</h2></div>
Parsoid HTML:
<h2 id="विकियात्रा_पर_आपका_स्वागत_है">...</h2>
Looks like something in the HTML here tripped up the pass?

| Resolved | ABreault-WMF | T373400 Bug in HandleParsoidSectionLinks - seems to skip some headings? |
Section links match by the ID from the TOCData, I bet parsoid's TOCData got confused. You should be able to check this by asking for the section info using the parse API.
I can't find the ticket where I investigated this at the moment, but I think the issue is because it's a compound template (or in this case recorded as a function),
<meta property="mw:PageProp/notoc" about="#mwt5" typeof="mw:Transclusion" id="mwCA" data-mw="{"parts":[{"template":{"target":{"wt":"#if:{{{content|}}}","function":"if"},"params":{"1":{"wt":"{{{content|}}}"},"2":{"wt":"{{#ifexist:{{{1|{{Documentation/docname}}}}}|{{ {{{1|{{Documentation/docname}}}}}}}}}"}},"i":0}}]}">we have,
} else {
// Legacy parser return null here
$metadata->fromTitle = null;that we exit early from,

There's some other discussions of Parsoid's limitations of templated section editing in T368095#9971720
