On an XFA enabled build:

1. Open https://www.canada.ca/content/dam/ircc/migration/ircc/english/pdf/kits/forms/imm5257e.pdf
2. On a text edit, for example, the one under "1. Full name" "* Family name", type "abcdef".
3. Hold Shift and press Home. 'abcdef' should be selected.
4. Press Delete.

Expected: 'abcdef' is deleted, field is now blank.
Actual: 'a' is deleted, field now contains 'bcdef'.

Also buggy with Backspace or typing something in step 4. In the case of typing something, it would be expected to replace the selection.
