 Description

If a call to the Maxima() function is extended to a second argument, this argument can't be deleted using backspace. in 6179 (stable) this problem doesn't exist. Also, after disabling Custom Glyphs plugin, the second argument can be deleted as usual.

Copy this to a math region and try to delete the empty string and the placeholder:

Maxima(f.x(a,b),"")

The maxima plugin is the current svn state (no local mods).

Yes, it is a drawback of SS-2423; currently all is around the IsCommonFunction property. If enabled, you can delete placeholders, but mouse/keyboard inputs are handled as if you have a common function (with name drawn to the canvas), the opposite if disabed. Have to figure out what would be the best approach to improve it.
