Images not appearing in Internet Explorer 11 when there is only one size

Hi,

I noticed that when you just use an array
global $glob_sce_settings;
/* Image sizes */
$glob_sce_settings['rwd_image_sizes']['s-team 2x'] = array(
array(275, 275, array('center', 'center'))
);

or one image size
global $glob_sce_settings;
/* Image sizes */
$glob_sce_settings['rwd_image_sizes']['s-team 2x'] = array(
'xs' => array(
275, 275, array('center', 'center'),
'picture' => '<img src="{single-src}" srcset="{src}" alt="{alt}">', // mobile-first strategy picture img.
'bg' => '', // mobile-first strategy bg.
'bg_retina' => '@media {dpr}, {min_res}',
'srcset' => '{w}w',
'sizes' => '{w}px',
),
);

the generated img tag on the page does not have 'src' attribute, which is required by Internet Explorer to show an image on the page.
<picture class="attachment-s-team size-s-team wp-post-picture">
<img srcset="//localhost:3000/wp-content/uploads/2019/11/photo-1500648767791-00dcc994a43e-e1574685299994-275x275.jpeg, //localhost:3000/wp-content/uploads/2019/11/photo-1500648767791-00dcc994a43e-e1574685299994-550x550.jpeg 2x" alt="">
</picture>

It would be wonderful if it could be improved in the next version. Thanks
