Yes. For more clarity, here is a simplified version of the whole control and even this I can't enter text in:

<TopLevelControl name="EditBoxSample" mouseEnabled="true">
    <Dimensions x="400" y="140" />
    <Anchor point="CENTER" />
    <Controls>
        <Backdrop name="$(parent)BG" inherits="ZO_ThinBackdrop" mouseEnabled="false" />
        <Label name="$(parent)Info" font="ZoFontWindowSubtitle" color="CFDCBD" wrapMode="ELLIPSIS" text="Enter text below:" mouseEnabled="false">
            <Dimensions x="400" y="30" />
            <Anchor />
        </Label>
        <EditBox name="$(parent)Text" mouseEnabled="true" keyboardEnabled="true" editEnabled="true" font="ZoFontWindowSubtitle" color="CFDCBD" 
                 textType="TEXT_TYPE_ALL" multiLine="false" newLineEnabled="false" maxInputCharacters="20000" text="Enter text here">
            <Dimensions x="400" y="90" />
            <Anchor point="TOPLEFT" relativeTo="$(parent)Info" relativePoint="BOTTOMLEFT" />
            <Controls>
                <Backdrop name="$(parent)TextBG" centerColor="000000" edgeColor="AAAAAA">
                    <AnchorFill />
                    <Edge edgeSize="2" />
                </Backdrop>
            </Controls>
        </EditBox>
    </Controls>
</TopLevelControl>

For some reason I can't click inside to get a beam or type anything. Although, a weird bug is that sometimes my keyboard will completely stop working inside ESO, almost like a text box does have focus, but looking anywhere on the screen I don't see what I am typing actually showing up anywhere, this isn't always repeatable.
