[🐛 in esl-popup]: popup wrong position when the first time shown

[dshovchko]

Sometimes there is the wrong position of popup. It looks like that as soon as the popup was shown it has height slight larger. Immediately after that, the styles were applied to the contents of the popup and the height changed. But the popup position didn't update. The result is a gap between the trigger and the popup.

To Reproduce
Steps to reproduce the behavior:

1. Select content of such length that it is on the verge of being placed in one line inside the popup. It is desirable that the content contains a link. Those, it will be shown at two lines without styles applying and it will be shown at one line with styles applying.
2. Try to open the popup.
3. This occurs only at the first opening.

Current behavior
If styles of popup content change the height of the popup it will have wrong position. But only at the first showing.

Expected behavior
In all cases, the popup must have the correct position.
