Autofill preview text can disclose sensitive information

[MEDIUM] Autofill preview text can disclose sensitive information
Autofill preview text can disclose sensitive information
The previewed text of autofill, shown to the user when the user hovers over an autofill entry, contains sensitive information and should not be accessible by the website until the user selects it. However, several vulnerabilities exist that can be used to steal the preview text.
1. Font side-channel attack
The font of the preview text follows the style of the field, making it possible to set the font of the preview text. The website can use a specially crafted font to infer the preview text, of which glyphs differ in size or font face.
(1) Size
Each character can have different width, and content can be inferred from size properties such as `scrollWidth.` Similar attacks have been proposed and patched in Chromium: crbug.com/916838
