调研方向
Start with lib/debug/breakpoint.rb around lines 192 and 241, comparing how paths are assigned for breakpoints. Reproduce the ERB breakpoint example and inspect show_bps output. Done means ERB line breakpoints display their file path while continuing to stop at the specified line.

描述
https://github.com/ruby/debug/blob/bead0984d241a91235e3d3bacd247f0363d2d530/lib/debug/breakpoint.rb#L192
The iseq.absolute_path seems to always be nil for .erb files even though the breakpoint works correctly and stops the execution
at the specifiied line in the erb file.
Therefore the show_bps is broken for such breakpoints showing only the line number:
break app/views/earth/users/index.html.erb:50
break
0 BP - Line :50 (line)
Should the mentioned code be changed to:
@path = iseq.absolute_path || iseq.path
like it is already done at:
https://github.com/ruby/debug/blob/bead0984d241a91235e3d3bacd247f0363d2d530/lib/debug/breakpoint.rb#L241
or should this be fixed at the ruby lang level and make iseq.absolute_path properly return the erb file's absolute path?
