Carousel Stuck on Last Slide

[CodyEddings]

My Flickity carousel in my Vue 3 Typescript app is being populated with slides dynamically at runtime via a for loop.

The problem:

Check out this video of the bug
The last slide added to my carousel is the only one that shows up, and when I try to drag the slide left or right my drag is ignored. Clicks to the slide navigation buttons or the page dots are registered and cause slide change callbacks to be triggered, but the slide itself never animates/moves/reacts at all to any of these clicks. For example: if my Flickity carousel contains slides that say "1" and "2", slide "2" (the last added slide) will always be visible and won't respond to navigation button/page dot clicks or dragging at all.

Where it gets really weird:

When I open up the inspector in chrome the Flickity carousel immediately starts displaying unique, scrollable slides. The same thing happens if I close the inspector after reaching this page containing the carousel; it "fixes" the bug.

What I've tried:

I thought that maybe the inspector opening or closing could be causing some sort of internal reload call for Flickity, so I tried to intentionally reload the carousel after I've added all of my slides, but it had no effect on the bug. Something unique is happening when I open/close the inspector in Chrome while the carousel is rendered that makes the last slide get "unstuck" from always being visible.
