NVDA is not reading out PDF signature field tooltips when using tab key

[Jennb422]

PDF signature field is not reading out tooltip when being tabbed to but only "Signature field is unsigned" is read out
When using the up or down arrow keys the correct information is read out but this should also be read out when using the tab key.

SignatureFieldTest (1).pdf

Steps to reproduce:

Open the PDF file and tab through the signature fields

Actual behavior:

When tabbing to the signature field all that is read out is "Signature field is unsigned" which does not give enough information as to which signature field is unsigned

Screenshot shows a PDF with 4 signature fields with tooltips and labels of Signature or one, Signature of two, Signature of three and Signature of four. It also shows the way NVDA reads out these fields when they are being tabbed to. It reads out “Signature field is unsigned”, “Signature field is unsigned”, “Signature field is unsigned”, "Signature field is unsigned" when tabbing over all 4 separate fields. This does not give the user the information of which signature field they are on.

Expected behavior:

When tabbing to the signature field the tooltip should also be read out similar to how it behaves when using the up or down arrow keys

Screenshot shows the same PDF with 4 signature fields but now it shows the results of what happens if you are using down arrow to read the fields. It reads out. “Signature of one (Click to sign) Signature field is unsigned” “Signature of two” “Signature of two (Click to sign) Signature field is unsigned” “Signature of three” “Signature of three (Click to sign) Signature field is unsigned”. This gives the required information to the user to be able to differentiate which signature field they are on.
