FakeVim's dot command fails if the last edit involves curly braces

Enable FakeVim and start with this in a .cpp file:

struct Test
{
    int func1;
    int func2;
    int var1;
    int var2;
};

Correct behaviour

1. Place the cursor at the end of "func1"
2. Press 'i' '(' ')' to insert parentheses
3. Press <Esc> to exit Insert mode
4. Place the cursor at the end of "func2"
5. Press '.' (dot command)

Result (correct): Parentheses are inserted at the end of "func2"

Wrong behaviour

1. Place the cursor at the end of "var1"
2. Press 'i' '=' '{' '}' to insert an empty initializer
3. Press <Esc> to exit Insert mode
4. Place the cursor at the end of "var2"
5. Press '.' (dot command)

Result (wrong): Nothing happens

Expected result: An empty initializer should be inserted at the end of "var2"

Reproducible only without ClangFormat plugin
