Subject: [PATCH] fix: disable_preview respected when preview_method != "load"
 (#577)

* fix bug of disable_preview

file should not loaded if disable_preview is true

* refeactor function open_preview about disable_preview

switch the condition checking `disable_preview` of `if`
move the longer condition to the `elseif`
swap their repective code blocks to maintain the same functionality

* refactor: simplify conditionals

* fix: missing then
