Can't remap to a sequence of keys that includes an i letter on the after part

[danielo515]

Describe the bug
Hello.
I'm trying to remap a leader+b combination to a sequence of keys. The problem is that, some of those keys include commands that are context aware and that depend on the previous key. Seems that the plugin is not able to "remember" the previous letter and just treats each one in isolation, so if you after sequence includes an i it will put it in insert mode, no matter you previously have an y

To Reproduce
You can try this remap

"before": ["leader","b"], 
"after": ["m","b","`","a", "y", "i", "w", "`", "b", "v", "i", "w", "p", "`", "a", "v", "i", "w", "p", "`", "b" ]

Expected behavior
I want it to execute the keys as a sequence, not each key individually

instead what you get is yiw... etc because the first a

Additional context

Funnily, if I change the order it works. This sequence works fine:

      "after": ["m","b","`","a","y","i","w","`","b","v","i","w","p","`","a","v","i","w","p","`","b"]

Both sequences you gave are the same. This works fine if you already have the 'a' mark set. If the 'a' mark is not set it will give the error 'E20: Mark not set' and then it should stop the remapping but currently it doesn't stop so it continues with 'a' being AppendAtCursor and then appends the rest of the keys to the buffer.
This will be fixed on PR #4735.
