toast controller in image bouncing is happening

Hi, we have developed using ionic 3. i.e I have added code to no-bounce

It is working fine for other pages which not contained an image.

we had toast controller to show respective information but the page is bouncing

Code follows please check below

in .html ::

in .ts ::

presentToast() {
let toast = this.toastCtrl.create({
message: ‘Reference: 4. Boehringer Ingelheim data on file (PREVICOX® 2007 Assessment Footprint).’,
duration: 5000,
//cssClass : ‘changebg’,
position: ‘bottom’

Can you please suggest/guide to fix this issue ASAP
