Memory leak / component v-if ?

[minaXU]

Memory leakage occurs when the v-if interface is used to switch components. However, the v-show function is normal.

I downloaded your case and did not find any memory leakage issues when using v-if in components And you haven't found any use of v-show in your case either

The second step was wrong. I updated the step and tried it again?
The v-show case is not written. Change v-if to v-show.
