I have an lwc with an input and a helptext like so*:
<lightning-input label="label1" field-level-help="pop up text"></lightning-input>
it correctly has a question mark next to the label, but the pop up text has no background so it is unreadable. I tried a number of css selector but none seem to work. Is there a specific one that works? I would prefer to avoid because it doesn't display next to the label, it displays above it like a separate line.
*I'm using Lightning out, calling the lwc from an Aura App which in turn is called from a visualforce page, unfortunately I cannot change this scheme.
