code folding icon hides break-point icon

[daxim]

1. Enable code folding.
2. Write a block so that a fold icon appears in the left-hand margin, e.g.

if {
}

3. Set a break-point in the line with the opening brace.

Expected: both the fold icon and the break-point icon should be visible in the left-hand margin.

Actual: fold icon hides the break-point icon.

this is consistent with other margin markers, eg diff

MonoDevelop? has a nice solution for this:

Markers for warnings, errors, and breakpoints are left of the line numbers, code folding markers are right of the line numbers.
