Learning: In tests (especially those using testing-library/dom/jsdom) for Rocket.Chat components, the HTML <code> element has an implicit ARIA role of 'code'. Therefore, screen.getByRole('code') or screen.findByRole('code') will locate <code> elements even without a role attribute. Do not flag findByRole('code') as invalid in reviews; prefer using the implicit role instead of adding role="code" unless necessary for accessibility.

64-65: 🎯 Functional CorrectnessThe reported attachment fields use
variant='inline', notvariant='inlineWithoutBreaks'. The new handlers therefore cover the affected path. No change toinlineWithoutBreaksis required for this fix.

- Around line 52-53: Update codespanMarked to perform only the existing
one-layer normalization and return the normalized value directly; remove the
subsequent re-escaping step so already escaped <, >, and & remain
correctly rendered, while preserving the surrounding code element output.

In PR #35863,
codespanMarkedandcodeMarkedcustom renderers were assigned todocumentRendererto prevent double-escaping inside code blocks. However,inlineRendererwas missed.When webhook messages submit attachments with
fieldscontaining special HTML symbols inside markdown inline code (e.g.,a>b \a>b`), the fields are rendered using. BecauseinlineRenderer.codespanwas not defined, it fell back to default behavior without unescaping HTML entities generated bynew Option(content).innerHTML, causing>to display as>on web while mobile rendered it asa>b`.This PR assigns
codeMarkedandcodespanMarkedtoinlineRendereras well, ensuring consistent inline code rendering across web and mobile.codeMarkedandcodespanMarkedtoinlineRendererinMarkdownTextInner.tsxvariant='inline'inMarkdownText.spec.tsx@rocket.chat/meteorpatch changesetIssue(s)
