[NcPopover] Provided 'title' property to trigger does not appear

[Antreesy]

Tracked it down to upstream:

https://github.com/Akryum/floating-vue/blob/19857764c4f73dea7ed44a7d970adb968ee7ad90/packages/floating-vue/src/components/Popper.ts#L504

this.$_swapTargetAttrs('title', 'data-original-title') is replaced and no longer shown by browser

It might interfere with upstream library hover behaviour, but there were no discussion about disabling/reverting it
Do we need a workaround here?
