Accessibility option for press and hold left click to simulate right click triggers left click and right click

[Anadon]

When trying to simulate a right click via the mouse accessibility settings to have a left press and hold register as a right click, what happens is that the instant it takes effect and there is a right click, there is also a left click. An example of this issue arises when you want to open a link in a new tab in firefox. You left click and hold, there's a flash of the right click menu, and then it follows the link in the current tab regardless.
