wxMaxima crashes ("assert ""gs_autoiIdRefCount[winid]!= ID_FREE"" failed in IncIdRefCount(): id should first be reserved") (probably related to the suggestions context menu)

[daute]

This is wxMaxima Git version ffbf97c on Windows.

Enter "1e5" (without quotes) place the cursor before the "1" and press the right mouse button.
Maxima responds with an error message:

assert ""gs_autoiIdRefCount[winid]!= ID_FREE"" failed in IncIdRefCount(): id should first be reserved

Here is a backtrace:

That (src/Worksheet.cpp:1827) suggests, that there is something wrong when building the suggestions context menu. Strange, but I don't see the solution now.
