2.0.17 vue-tsc error - multiple event properties with different modifiers returns TS1117: An object literal cannot have multiple properties with the same name

[synthmusic]

vue-tsc throwing error on component with multiple @keydown events with different modifiers as of 2.0.17.
Does not reproduce in 2.0.16

vue-tsc --build --force

with component that includes

<input
  @keydown.esc="handleEsc"
  @keydown.down.prevent="handleDown"
  @keydown.up.prevent="handleUp"
  @keydown.tab="handleTab"
/>

results in
