Edge New PDF Reader form security bug
Edge can not display a certain PDF under the following conditions. Edge "New PDF Viewer" feature is enabled at "edge://flags/#edge-new-pdf-viewer". A pdf is encrypted with the security setting of "Changed allowed" as "Filling in form fields and signing existing signature fields". Showing and Hiding texts with Acrobat form Javascript does not work properly. Notice: a. Adobe Reader works as expected. Chrome PDF Viewer works as expected. Firefox works as expected. Even Edge old pdf viewer works as expected. b. If a PDF is not encrypted, the same PDF works as expected. Example: https://www.shtml.jp/test/202412/edge_form_2024_security.pdf ShowText button and HideText Button does not work as expected in the case of Edge with "New PDF Viewer" enabled. The Same pdf with no security https://www.shtml.jp/test/202412/edge_form_2024_nosecurity.pdf Both ShowText button and HideText Button does work as expected in the case of Edge with "New PDF Viewer" enabled as well.
