Fix scrollbar markers in large files (#10181)

#10080 introduced a minor change in how the min marker height is
enforced. Before the change, it was applied to the aggregated marker,
but after the change it's applied to each individual marker before
aggregation.

The difference is not noticeable on small files, where even single row
markers are higher than `MIN_MARKER_HEIGHT`, but it leads to visible
differences in large files with repeating blocks of highlighted and
not-highlighted blocks, like in [this
case](https://github.com/zed-industries/zed/pull/9080#issuecomment-2006796376).

This PR fixes how the `MIN_MARKER_HEIGHT` is applied.
