Indentation jumps to right when editing generates invalid code

Consider the following code (cursor is marked with `|`):

typedef struct S {
    int i;
    long l;
    float f;
    double d;
} S;

int main()
{
    S s = {.i = 1|, .l = 2, .f = 3, .d = 4};

    return s.i;
}

I want to change the line to

S s = {.i = 1}; //, .l = 2, .f = 3, .d = 4};

so I press `}` and immediately the whole code is indented two times (see attached video).

This also happens with `-tcs`, but I think depending on tab settings and previous/next lines the indentation can be much higher.

The indentation is corrected once `;` is pressed but the effect is really annoying and makes you think you did something wrong.
