.cmdline() method not working

[Ruben-Arushanyan]

In most cases, the vimWasm.cmdline() method does not work as expected. I anticipate that cmdline() should function similarly to manually using Vim's execution mode.

Here are examples of bugs:

• vimWasm.cmdline('startinsert') should change Vim to insert mode, but it does not work.

• vimWasm.cmdline('2') is supposed to move the cursor to line 2, but I don't see the cursor updating. Even after trying to redraw vimWasm.cmdline('2 | redraw'), it still doesn't work.

@rhysd Please help to find solutions. Thanks
