[WilcoFiers]

The frame-focusable-content rule should not fail Passed Example 2 of the iframe with negative tabindex has no interactive elements ACT rule.

<iframe tabindex="-1" srcdoc="
  <a href='/' tabindex='-1'>Home</a>
"></iframe>

@padmavemulapati what does your test HTML look like?

[padmavemulapati]

Validated with the latest develop branch code base, when we run axe inside iframes and frame has negative tabindex , then
frame-focussible-content rule is passing
Script:

<iframe tabindex="-1" srcdoc="
  <a href='/' tabindex='-1'>Home</a>
<script src='/axe.js'></script>
"></iframe>
<script src="/axe.js"></script>
