Why are the results produced by the ui-autocomplete plugin not displaying correctly in Firefox?

Question

JavaScript

Hello, there is a site Link to the site (login: demo , password: demo).
When you enter cities in Russian into the field from/to where (for example: Kyiv), the ui-autocomplete plugin is triggered.
In Chrome, everything is fine, but in Firefox 60.0.1 (not at all resolutions), the text of the list items "flies" to the right.

I went through all the containers of tabs (since they obviously push out), but the result is zero.

What is the problem?

Thanks in advance.

Answer 1

All browsers have different preset css settings + personalization incl. you need to use something like cssReset/normalizeCss to bring everything back together.
In the code inspector settings, turn on the display of browser styles in order to be clearer.

Answer 2

make ui-autocomplete position: absolute;
