In Firefox, parent element won't get focus when child with fixed position is clicked -


i have fixed element inside focusable element. when click fixed element, parent focusable element should receive focus. works in chrome, edge , ie11, doesn't work in firefox.

.focusable {    background-color: red;    width: 200px;    height: 200px;  }    .focusable:focus {    background-color: blue;  }    .fixed {    top: 200px;    background-color: green;    position: fixed;    height: 100px;    width: 200px;  }
<div class="focusable" tabindex="0">  <div class="fixed">  parent not focus.  </div>  </div>

do know workarounds? avoid handling mousedown event , calling preventdefault().

because using position fixed inner child element

removing position:fixed , work fine

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
