RTLIL: Top module with selected module

[towoe]

I have question regarding the returned value for RTLIL::Design::top_module().

I used this method in a pass to get the top module. This worked fine until I tested it in combination with a select command.
Here the top module was not the same as without the selection.
When using the command hierarchy this shows the 'actual' top module regardless of selected modules.

From the implementation it is clear that only the selected modules are considered to find the top module:

yosys/kernel/rtlil.cc

Line 593 in 5c1e6a0

for (auto mod : selected_modules()) {

Is this the intended behavior?
