[SF][A11y][MessageStrip]: repetitive screenreader announcement when link is provided

[caroline-ferri]

Bug Description

Our current design has a message strip that has text and a link at the end of the text. When the screenreader user focuses on the link within the message strip, the screenreader announces all the text (including the link text) to help annotate the message strip. The screenreader then repeats only the link text to give context to the actual link. The SF A11y team has reported that this repetitive announcement is an a11y violation and should be avoided.

Please note that the SAP UI5 MessageStrip component supports a link property and does not have repeated announcement of the link text:

SAP UI5-WC announcement:

Affected Component

MessageStrip

Expected Behaviour

When the user navigates to a link within the message strip, the link text should only be announced once when focused.

Hello @UI5/ui5-team-ctr-ril,

Could you please take a look at this? Issue is reproducible as described above, compare announcement on webc sample vs ui5 sample.

Best,
Siyana
