ru_RU is jumping between main and symbols modes

Keyboard's bottom row is visually jumping between "main" and "symbols" input modes.

Cyrilic/Russian keys are generaly narrower than their latin layout counterparts, just because there are more of them in one row; and bottom row's keys are using top row's "normal key" to calculate their sizes.

But "symbols" layout has the same amount of keys as a latin one, which is why it looks alright in e.g. en_US, and anyway it has its own "normalKey" to use as a reference.

It doesn't happen (as much) on Android: only Shift and Backspace keys are slightly jumping toward the center. Although due to the lack of visible borders, it is harder to notice or measure without pixel ruler.
