Anim is reset when tabview changes


I’ve set a event_cb to start the anim when I select the third page.
But wondering why the anim is reset when the tabview changes the value(the tab selected).Is that a built-in func integrated to the anim’s setting?

Screenshot and/or video

If possible, add screenshots and/or videos about the current state.

OK I see after checking the doc.
lv_anim_start means creating one anim that uses the properties i’ve set.
So when I return to the third page,the anim is created again. It just seems like ‘reset’.
Is that way?
