Repeat command is broken with execute-keys from insert mode

[alexherbo2]

How to reproduce

1. Add the following setup:

map global insert <space> '<a-;>: insert-space<ret>'

define-command insert-space %{
  execute-keys <space>
}

2. Then type:

i<space><esc>.

To simplify it, it also happens without calling a command, and without using a mapping>

• execute i<a-;>:exec t<ret><esc>: one t is inserted
• execute .: tt is inserted
• execute .: ttt is inserted

For every repeat, it increases the number of ts in the repeat list by one
