Insert both characters if a dead key combination is not recognized (e.g. ‘a → á, ‘b → ‘b)

When I use any variation of English, US international (with dead keys,altGr dead keys or alternative) on my Linux Mint machine I always encounter this behaviour.
When I press one of these keys: ' " and then follow them with a ‘non-accentable’ character like a [ or a b no output comes out at all.
