[JarrettChan]

Bug Description

Affects menu popover, overflow shellbar items popover.
Hover does not reveal the full text.

Hi @SAP/ui5-webcomponents-topic-p
This issue is about long text being truncated in the Shellbar Popover.
Perhaps it should be wrapping instead.

[dobrinyonkov]

Hi @JarrettChan, according to the visual design of the component, the text inside the menu items should not wrap, but truncate as implemented. Please use the title attribute to show a tooltip with the whole text when an item is hovered.

<ui5-li title="Very long text that truncate...">
    Very long text that truncate...
</ui5-li>

Kind Regards,
Dobrin

@dobrinyonkov , Ok I can probably control the menu popover ui5-li since I believe it's copied over from the [slot="menuSlot"] but not the overflow popover ui5-li since that's defined by ui5-shellbar
https://github.com/SAP/ui5-webcomponents/blob/main/packages/fiori/src/ShellBarPopover.hbs

Please help with the ui5-li in the overflow popover

Hi @yanaminkova, @dobrinyonkov,
My a11y colleague rejected this solution as the tooltip is not visible to keyboard or touch users.
Could the overflow list use wrapping-type="Normal" for an overflow title to be accessible to keyboard or touch users?
