[Mobile devies] Cannot open tooltip again when call this.$root.$emit("bv::hide::tooltip")

[Trientq1]

Describe the bug

I implemented b-tooltip on my website, but I am encountering issues with it on mobile devices. Specifically, after adding an event that triggers this.$root.$emit("bv::hide::tooltip") on page scroll, the tooltip closes as expected. However, when attempting to reopen the tooltip by touching it once again, it does not respond.

Steps to reproduce the bug

1. Touch on Title, the tooltip will be appear
2. Scroll page
3. Touch again on Title
4. Cannot open the tooltip

Evidence

Expected behavior

Can open the tooltip again
