Description

Current behavior

I cannot find(Component|".selector") but I can see it via html() and via .contains()

Here are the most important parts of code. (I am using ava, t.log is the test logger)

I am using a styled component here but it is the same when I add a custom className, id or data-attribute to attempt finding the element/Component.

code

const RetryButtonId = RetryButton.styledComponentId;
const retrySelector = `.${RetryButtonId}`;

t.log(retrySelector);
const retry = wrapper.find(RetryButton);
const _retry = wrapper.find(retrySelector);
const html = wrapper.html();
const match = html.match(new RegExp(`<button class="${RetryButtonId}.*?">Retry</button>`));
t.log(`match: ${match && match[0]}`);
t.log(`length "${retrySelector}": ${_retry.length}`);
t.log(`length "RetryButton": ${retry.length}`);
t.log(`exists "${retrySelector}": ${wrapper.exists(retrySelector)}`);
t.log(`contains "RetryButton": ${wrapper.contains(RetryButton)}`);

The logs show inconsistencies. While contains() returns true, exists() returns false.

The html() matches the element but find() and exists() ignore it.

Logs

ℹ .sc-jTzLTM
ℹ match: <button class="sc-jTzLTM dlKhUw sc-bdVaJa kgpquR">Retry</button>
ℹ length ".sc-jTzLTM": 0
ℹ length "RetryButton": 0
ℹ exists ".sc-jTzLTM": false
ℹ contains "RetryButton": true

Expected behavior

contains(), find(), exists(), html() should return matching results.
