Highlighted comments fall off bottom of returned essay

# Highlighted comments fall off bottom of returned essay

On a returned (graded) essay view, some highlighted comments near the end of the document fall below the visible viewport and aren't reachable through normal scrolling.

## Reproduction

1. As a student, open a graded/returned essay with comments anchored near the end.
2. Scroll to the bottom of the document.
3. Observe that some highlighted comments are positioned below the rendered scroll extent.

## Expected

All comments are reachable. The page extends far enough that comments anchored near the end are visible.

## Actual

The viewport stops short of the last few comments. Students miss feedback on the conclusion / final paragraphs.

## Impact

Conclusions are precisely where teachers' most synthetic feedback often lives. Missing this comment band hides feedback the student needs. Reported 2026-05-01.

## Affected versions

Reported 2026-05-01.

## Suspected cause

Scroll container height doesn't include the comment overflow — likely the comments are absolutely positioned beyond the document's intrinsic height and the container clips them. Adjust the container's min-height or padding-bottom to accommodate the lowest-anchored comment.

## Workaround

None. Students simply don't see those comments.
