selected and postOnEsc for enterFindMode

[ghost]

I'm curious about the usage of these two commands, haven't notice anything differences after remove these two and hardly find hint in the source code.

The parameter of selected (aka. selected=true) means FindMode should auto use selected text to execute a query at once.

• This parameter is enabled by default, and you may disable this behavior by appending selected=false into map xxx enterFindMode

postOnEsc is also a boolean (true/false) parameter while it's disabled by default. It means to execute a postActivate action on FindMode receiving an <esc> key.
But, during my test on Chrome 119, this seems to fail as you said - maybe you can forget it...
