[Bug] New <modified> tags are not rendered

[JohannesBuchner]

Describe the bug

Claude now outputs code like this:

<changes>
<change>
<file>megadifflike.py</file>
<description>Refactor: ...</description>
<original>def build_joint_bounds(param_info, lb, ub):
    """Build bounds for the full parameter vector."""</original>
<modified>def compute_physical_bounds(params_defs, sampler_paramnames):
    """Compute physical parameter bounds, adjusting for normal priors."""</modified>
</change>
<change>
    ....
</change>
</changes>

This is not rendered well in the interface:

Expected behavior

Not sure what would be best, but easiest would probably be two divs with original and modified below each other.
